We are judged every day by others whether we like it or not. However I have learnt that you can't please everyone in life. If you do your best, then that is enough.

I think people are trying to live up to their own expectations, and they must be proud of this. But actually, some other's expectations do affect their own judgement and decisions.

Happiness is all we want. As long as we are truly happy from one moment to the other, it doesn't matter whose expectation that is. Time goes by, life goes by. Enjoy the moment, then there is no other's expectation nor mine.

I think everybody does to a certain extent.

I think that even if we are not living up to someone else's expectations, we step outside ourselves (becoming an Other) and live up to our "own" expectations - which nevertheless do not really come from inside, being, as they are, merely internalised versions of what the culture we grew up in (for example) has been drumming into us since birth... So the short answer is yes, we all do because we can't avoid it...
