Learn To Appreciate Yourselves:

People at times are full of resentment to themselves for they did not reach the goals they had in mind or because their surroundings had cretin expiations of them or because the don't fit into societies definition of success.

Each person is very unique, each person has his own talents and weakness, each person has his own likes and dislikes, so that pattern of society of do well at school, get a degree, work in a respectable job, make money, marry someone to have a mortgage some kids and a white fence with an occasional golf game with the friends can not be every body's definition of happiness and success, yet people keep doing what is expected from them and are chasing that collective dream that they were thought growing up, thinking that it's their own personal dream to realize once they achieved it that they were chasing an empty shell ( I think that's the reason for a high divorce rate and that's the reason for those mid life crises). 

I believe that people should evaluate them salves by how happy they are with their choices but most importantly, I think people should evaluate them salves threw the way they handled things that happened in his life, I'll give an example:

A man who had a successful company and things happened and he is in a place where the ground just crumbled beneath is feet and he lost everything he worked for and now for survival, he needs to accept any job that he can get even as a dishwasher as a survival act. Sure some people will glow from hearing about it, and some people will feel sorry for him, but I think such a person should be admired for he has a very strong survival skills (and we all know what Darwin's said about that) he did not let his ego blind him, he swallowed his pride and he accepted any job although knowing what people will think and talk about him and even tough it is a fall from his former status, he adjusted his strategy according to the circumstances that took shape.

So please remember to evaluate your salves correctly, don't be so harsh on yourselves, and don't hurry to judge yourselves, everything is dynamic and changes constantly, and we are all very different from one another, so stop care what other's might think of you, the only thing you should care about is your own personal truth.
