my university life

Honestly speaking, my university life was a bit of shit. I am not joking, the time during my last five years was fulled with ridiculous, because I waste a lot of time but nothing to do. I can not find my road to the future. I play computer games or taking a bike with my high school student. I regret what I did strongly for the next three things:

1. I did not make my school course well or qualified, which directly take me to the fifth school life.
2. I can not get well with my roommate. Sometime I even can not go sleep well for him but I have no courage to live or talk in a man way. Also, I did not have some new good friends of university.
3. I did not go to my library usually. Now I did not have enough time to read some books, but I used to have so much valuable times to do something meaningful. I was so regret about my last five years.

I become a lower student from top I was. I was so hope that someone told me how precious I will have five years ago. But it was to late, all I have was a silly graduation certification and a useless body. Hopefully, gods did not shut down all my doors. I met Mr.Dong, a technical director in a medical company. Althought I was in a small company, I must hold toughly my opportunity to make my success. I can not forgive my mistake I have make, the only way to make up is to learn crazy.
