Are both correct?

If so, what are the differences in meaning if any?

The first version means you felt happy when you managed to improve something. The second one means you were satisfied with the results, having managed to improve it or having done that improvement especially well.


Only “I was happy with my improvement” is grammatically correct.

Similarly, "I was happy about a situation" is correct.

You can't be happy at something or someone, just like you cannot be sad at something or someone.

The correct usage of happy at would be involve a time or place.


  1. I was happy at that time.
  2. I was happy at work.

  • Joe, this is still inadequate - I think you’re statement that “happy at” is restricted to time or place is simply wrong, and you’ve provided no link to a published reference to support your claim - but the question was low quality (which is why it’s on hold) so it may not be worth the effort to improve your answer.
