How then do I mange the expectation of people on me such that i don't get into depression when I'm unable to meet up with it.?
It's almost like everyone knows you're going to succeed but don't even care about what you're passing through while you're striving to make them proud.
Well, it is easy to say to not mind what others are saying or what you feel of your percieved expectations from them but in reality, it is just hard to apply to oneself. It is a combination of self and social awareness which will always be a part of our daily experiences. However you ciuld manage how you would react on those expectancies you view from them. Indeed it could be either positive or negative; to some people it inspires them to prove other people wrong which helps them to strive for the better. But to some people it drags them due to pressure.
What I mean with controlling how you would react in those situations is to try maintaining your composure. We cannot control how others will think and view of us. Focus on what you are doing and follow your plans. Consistencywill always put you to success and that only means keeping your eye on your way despite of distractions.
