Recently, I had talked with my friend and read my friend's blog. I just realize that I slightly forgot some of the important principles.
You have to "give up" something in order to "get" something else because you can't obtain two things in the same time.
If you get something, that is your reward. You should appreciate it. But, if you cant get the things you want, you still happy. This reason is you never lose anything before and you never obtain the things before.
Nobody heart is grow in the middle of your body. Thus, you no need too mind if someone bias.
I understand and happy now ~ Thus, dont worry (*^_^*)
