In my native language, we use an idiom to warn someone that they're doing something which has no result at the end:

Trying to convince him is like squashing water ...

Is there any idiom in English with the same meaning?

    I would note that most English speakers will likely understand your translated "squashing water" comment - as a matter of fact, I am going to try to remember that, that's great!

There are a few idioms like that. One is:

You're just beating your head against the wall.

another is

Like trying to squeeze blood from a turnip.

and another is:

It's like trying to herd cats.

They each are used is slightly different situations. To be most analogous to your expression it sounds like I'd use the first one: Trying to convince him is like beating your head against the wall

    I'm (UK) more familiar with blood from a stone, rather than turnip.

    For me, "herding cats" implies that it's difficult or exasperating, but lacks an element of pointlessness. I sometimes describe setting up meetings with busy colleagues as "trying to herd cats", but I do want to meet with them--it's just hard to get all of them to agree on a time and place.

Sisyphean labor. "Sisyphean" means endless and unavailing, as labor or a task. Comes from Greek mythology, Sisyphus was made to roll a giant boulder up a mountain as punishment by the gods, but the boulder would always roll down before he could get it to the top, forcing him to begin the pointless exercise anew.

    I LOVE Greek and Roman mythology. They had some cruel punishments in Hades. My favorite was Tantalus who was placed in water up to his neck but if he tried to drink, it would drain away. And there was delicious food floating around his head that would fly out of reach if he tried to grab it. It's where we get Tantalize from. Commented Apr 13, 2012 at 14:43

To add to the other good examples:

Rearranging the deck chairs on the Titanic.

This is my goto for these situations because I think it really creates a nice visual of futility.

    It does but it also conveys a vision of impending catastrophe which does not appear relevant. Still a nice image though.

    I've always thought "rearranging the deck chairs on the Titanic" is intended to convey not merely a sense of futility but more specifically of focusing on the mundane in the face of an overwhelming need to focus on something much more pressing. "Fiddling while Rome burns" conveys the same meaning to me. Commented Apr 13, 2012 at 23:01

There are very many idioms that you could use for a Sisyphean task. Take your pick.

  • I think the most generally applicable would be "pushing water uphill with a rake".

  • If you want to say that you're doing the right thing, but you're doing it too late to have any effect, you'd say "shutting the stable door after the horse has bolted". This is sometimes known as "stable door shutting" for short.

  • If you want to say that there are too many unpredictable factors to make your task possible, you'd talk about "herding cats".

  • If you want to say that you're trying unsuccessfully to get someone to do something or give you something, this is "trying to get blood out of a stone".

Plus all the other excellent suggestions in the other answers here.



It's a fool's errand


I would use ... like beating (or flogging) a dead horse
It even has its own wikipedia entry

I would not use Jim's suggestion beating my head against the wall with the word like - so

  • I am banging my head against the wall trying to convince him

  • Trying to convince him is like flogging a dead horse.

are two ways of expressing your problem

If the original is Water naar de zee dragen then it is a Sisyphean task

    Beating a dead horse has a different meaning. Beating a dead horse means that the topic has been thoroughly covered and there's no more use in going over it any more. I've never used it heard in this context.

Like trying to carry water in a sieve

Like trying to empty the sea with a thimble


I did a search for "is like trying to convince a" and came up with a lot of really amusing results:

like trying to convince a cat it wants to go swimming.

like trying to convince a cat anything.

like trying to convince a two-year-old that a shot won't hurt.

like trying to convince a five-year-old that vegetables taste like candy.

like trying to convince a pacifist that violence solves everything.

like trying to convince people that "white trash" is derogatory and "redneck" isn't.

like trying to convince a mouse that the cat is her best friend.

like trying to convince a corpse that physical therapy is the only answer to its problem.

like trying to convince a newborn that crying is illogical.

like trying to convince a scientist that the moon is really made of green cheese.

I like

In the specific case that you are trying to convince to someone who will not listen, you are talking to a brick wall or a blank wall.


English is not my native language

Something that fits and has not yet been mentioned:

*Substitute treacle for your local high-viscosity liquid.

Usually used in the context of assigning useless busy work to keep employees busy when there's no real work to do.


You're on a hiding to nothing trying to convince him.

It means that your possible outcomes range from heavy defeat (a hiding) to nothing, and they exclude even a minor victory. It's not quite as evocative as other idioms, but it's commonly used.


An example would be "a wild goose chase". An example of the use of this is:

I tried to tell him he was going on a wild-goose chase.

The Online English Wiktionary states that:

Early recorded use refers to a type of 16th century horse race where everyone had to try to follow the erratic course of the lead horse, like wild geese have to follow their leader in formation.

Barking up the wrong tree

Wikipedia: if you are barking up the wrong tree, it means that you have completely misunderstood something or are totally wrong.


"Tilting at windmills" a reference to Don Quixote who imagined the windmills to be giants attacking a village.


There is a very similar idiom in English, treading water, but it doesn't exactly fit into the sentence you've provided. It means working very hard yet achieving nothing.

We've tried to fix it, but it's as if we're treading water.

  • I always thought that treading water meant an idle task, as you don't get anywhere. I don't see where your "working very hard" comes from.

How about "He might as well be pissing on a forest fire" ? Totally futile.


Here are two from Sting's "Be Still My Beating Heart" (from ...Nothing Like the Sun [1987]):

"Never to be wrong,
Never to make promises to break.
It's like singing in the wind.
Or writing on the surface of a lake."

I came here to add "Pissing in the wind," as that's quite common, but already mentioned. However, I haven't yet seen "Pissing up a rope" mentioned. That one is sometimes used as an insult (e.g. "He can go piss up a rope"). It's possibly a corruption of "pushing a rope," also a fairly futile thing to attempt.

I think "talking to a wall" is a good option, especially if you rephrase your original slightly: "Talking to a wall would be as effective as trying to convince him of anything."



If the intent of the usage is to point out the non-durability of one's efforts, which is to say that what we do will vanish in time, then the song "Dust in the Wind" by the musical group KANSAS provides (uses) phrases like:

  • Everything is dust in the wind
  • All we do crumbles to the ground
  • Nothing lasts forever but the earth and sky

Beat the air or beat the wind - to carry on making futile efforts. In my native language, we`ve an identical idiom in meaning. Crush/squash the water.

The closest thing I can think of to "squishing water" is "nailing jello to a wall".


nail Jell-O to the wall phr. to do something that is totally futile. (Jell-O is a protected trade name.) You’re wasting your time. Trying to get him to do that is like nailing Jell-O to the wall.
