What to do after College?

So Im a senior this yr coming up. I am majoring in Biology and minor in chemistry. My dream is to become a Doctor. But due to me being lazy my GPA isn't as high as it should be. 3.2 right now. Its good but not as good as some other students. I don't know what to do. I will be in debt when I get out. So I need a good paying job to pay it all off. There are times I ask myself why am I in biology. But I really do enjoy science. If I don't get into medical school I would like to go to graduate school for genetics. All I can do now is pray and ask God to lead me somewhere. Where I can be successful. well I just had to rant about that. until next time!
