Everyday someone says that they regret one thing or another that has happened to them at some point in their life. If I had the choice to, I wouldn't. Know this probably sounds crazy, but if I had the chance to do my life over again I would decline. Why would you risk who you are today? The people in your past were in your past because they helped make you who you are, not who you want to be. When you get into high school sometimes you begin to feel as if the world has abandoned you, and your left alone to fight the world. This is when you learn who your true friends are and who are not. If you went back in time and changed your past, you wouldn't have what you have today. You could make your life worse. Most people don't realize this, when you change something it can be for the better or for the worst.
I would not under any circumstances change who I am because I do not want to be who everyone thinks I should be I want to be the person I am & that I want to be. In life, look at your own standards and set your standards high. Your standards being the guys you date, the friends you hang out with, and even the people you choose to dislike.
As we grow up, we learn that even the one person that wasn't supposed to ever let you down probably will. You will have your heart broken, probably more than once, and it's harder every time. You'll break hearts too, so remember how it felt when yours was broken. You'll fight with your best friend. You'll blame a new love for things an old one did. You'll cry because time is passing too fast, and you'll eventually lose someone you love. So take too many pictures, laugh too much, and love like you've never been hurt because every sixty seconds you spend upset is a minute of happiness you'll never get back. Always remember that to someone somewhere you mean the world to, even if to the world you mean nothing. And ALWAYS give everything if you truly love, never hold back for fear of striking out.
