                                                               Community College

     Here I am, a senior. After four years of high school, I have learned a lot of lessons. Some were

good and valuable. And I have also learned others just from growing up and being around other

teenagers.

     I started senior year with a 1.5 GPA (=grade point average平均分,相当于65%), which is not

even close to what I am capable of. The last three years I fooled around and cut lots of classes. Now,

I can easily say that it is the only thing in life that I regret. Next year I will watch most of my friends go

to college while I lost that chance. This does not mean that I am giving up on my dreams, but when I

started high school, my goal was to get great grades and go to a competitive college.

     At first I blamed the people around me for my bad experiences, but I've learned that it's my fault

when bad things happen. In the last three years I realized that I am the only one in control of myself.

While making my teachers and my peers the excuse for not wanting to go to class, I developed a huge

lying problem.

     If I could start over, I would in a heartbeat, but I can't, so instead of beating myself up, I try talking

to younger teenagers about the importance of doing well in school by explaining the situation I got myself

into. Community college looks like a great opportunity. I am looking forward to taking many credits and

receiving good grades. I see community college as a year to turn my life around. It's my ticket out of here

to wherever I want to go. I have another chance to make my future and I've promised myself I won't

mess up.

     We need to study history so we won't repeat our past; I've studied my personal history, and will

avoid my mistakes in the future. I am ready for the next task in life, the only question is, is it ready for

me?
