where is me?

once, a friend of my had a sentence to me is: it's easier to understand and know others rather than yourself. somehow, he is right but I dont think so. 

what the influence tactics can I use? how to influence ? how to promote myself ? clues...........

after you, I dont know how to trust others and lost myself, kind of. I still want to be me but who I am? what's the right direction can you please show me around?

a month later, I will have my final tests, panic, anxious, not confident, do you hear my pray?
