Study and life is the process to help each other.
If I five years younger, I would study harder. May, results are not very good, but at least I pay, so I won't regret.
For life, I will have more opportunities, this time, I won't let chance slip through your fingers, hold on.
I think, if I were five years old, my life will be a lot less regret. However, the present is the most important. Study hard, good life!
