"Life is to deal with the ambiguity."
In the school, workplace, and sport, we need to deal with a lot of things such as doing the homework, submit tons of papers, prepare for the presentation, elaborately stretch out the body so as to do our best performance, listen to our bosss opinion no matte how bad the boss is, and so forth.
We never know how we are going to be. You might be a doctor, baseball player, soccer player, officer, teacher, factory worker, and so on. If you wanted to be a doctor when you were a kid, you might want to be a factory worker.
Life is hard. Its getting much easier to acquire new information but hard to figure out how others feel. We need to accept others, and understand them.
Anyway, have a wonderful day.
