We have to open our eyes to see the true fact of everything

I used to be, even now, a person who only look for the benefit that i can get from everything. If there is a benefit, then I will do it or achieve it by all means,even in the bad ways. I used to be a person, even now, who only judge everyone on their face and outlooking. If they are beautiful or strong, I will be blad to sacrifice everything for them. But after I experience several big things, I start to consider whether it is right or not. I found that I was miserably mistaken and I will think more carefully about what attitude I should take toward everything I meet.
