In some languages (for example Russian) there is a very famous phrase about something that is forbidden or not possible, but can be done if very desired.
Если нельзя, но очень хочется, то можно
Direct translation would be "If it is forbidden, but very desired, then it is possible".
It can be applicable for anything, like for science/technology in a good way, for people relations in a bad way (like it is forbidden to have a mistress, but if you really want you can) etc.
Is there something like this in English?
I found one by Oscar Wilde "The only way to get rid of a temptation is to yield to it", but can it be applicable not only to bad things like alcohol etc, but to science, technology?
For example, if it is well know that computer program cannot do this, but someone really did it. Can this phrase be used in that case?
Or maybe there is phrase which can be used in science/technology only. I am looking for this one (for science/technology).
Let's say (artificial example, of course) I am writing an article about possible ways to travel faster than light, or to travel to other stars, and I want to use it as an epigraph.
UPDATE1: Can I use phrase from Alice in Wonderland? "The only way to achieve the impossible, is to believe it's possible." but I think it is from movie, not from book.
