not everyone in this world is what you expected to be like.
nobody is this world is perfect, including yourself.
and yes.. you're a perfectionist. thus, it leads to what you are today.
you are not born to be self-centered nor an introvert.
it is true that today's society is so competitive to the extent that many just decided to jump from the 100th floor to end their lives.
(ahh well. it is a very serious crime now.)
okay. so everyone have to put in their utmost effort.
i congrats you since your effort had been paid off well. (:
but this does not mean that you can treat your friends like puppets bcus they are mere "useless" to you.
please admit the fact that friends are impt in one's life.
soon.. you'll lose them one by one if these continue to go on.
life sucks. i agree.
