because alot of people prefer you to be who you not than who you are
*people expect you to be perfect, even when they are not,it is a normal expectation
I believe it is better being urself (who u are inside). However one thing i have learnt in life as a young man is to continually work on my personality.
In this 21st century, you need a good personality in everything you do, work, school, ur local community e.t.c. So you may have to bend your true self a little bit to display this charateristics. But the bottom line is that you understand who you are yourself,so you dont feel like your living another life.x
