I agree with Iou, or whatever his name is. But another thing I want to point out for those who can't make decisions for their future, is, if you have a plan, there is some way it can fail. Actually, I even tried it myself. I guess you need to make good decisions. Is your heart beating really fast? Do you have an unrest in your stomach?
And, I want to point this out: you never know what will happen tomorrow. Stick with it today, or try something new today. Religion, or your lifestyle connects with this theory. If your Christian ( like me ) you never know what will happen, and you need to be sure if you will go to Heaven if you die, or something else. Always be prepared.
And even more for those in college like me, you should be thankful that you are at least in college. There are many people who wish do be like you; those in North Korea, Africa, everywhere!
I'm not saying this because my grades are good, they're pretty ...hmm...regular, but because if you fail once, it's not the end of the world.
Look at your life on the bright side. I focus on the good things in my life; I'm so joyful of living in God's mercy, grace, and love. And help others. Good luck, guys!
