Be you.

It's better to be hated for what you are than to be loved for something you are not.
Stop caring for yourself(like obsession) and you will automatically care less about what people think of you.

Stop beating up yourself for everything that has gone wrong, Its not your fault every time. Do your part.
And It's not wrong to observe people may be you are wasting time by doing it just look after it. 

This moment is what defines you.
What you prioritize is what matters.

Between going with the flow and things that drive you but subsided by petty issues of yours.

What matters you, what drives you is what makes you content.
What is important for you now!! at the moment. Is what is needed. Everything else can wait. Things may be important to you but at the moment only one thing matters, choose that and work on it. Note down the other things and schedule them.
