Throughout life you will have many decisions to make. Some will be simple and some more complicated. In making those decisions make sure that you are doing what is best for you. A lot of times we do things with other people in mind and in some situations that is fine. I am saying that as you progress in life and you start making decisions that can change the course of your life make sure you are choosing what is best for you.
What you also need to pay attention to as you grow up is trying to "Fit In". Don't try to fit in where you don't belong. Don't who you are or what you believe in just to fit in with others. Changing who you are would be like trying to fit a square block into a round hole. It doesn't fit at first but if you continue to sand the corners of that block eventually it will fit. It will be round enough to fit. But in doing that, the square block looses what it was that made it unique. Now it's just like everything else.
Most important thing that you can do for yourself is to take a step back and do a self evaluation. Ask yourself are you who you thought you would be? If not, am I better or worse than I thought I would be? How did you get to where you are now? What do I need to change to get to where I want to be?
Doing this for yourself will be the best decision you can make!
