if you want to change, "later" is a word you can't use. Postponing your change is what's stopping you, every time you get motivated to do something you think to yourself "Tomorrow for sure". But the next day nothing happens and you remain what you hate. Use this moment of determination to do what you want to do, don't waste it writing a comment. Go out, head back here and tell us that you did indeed go out and not that you will go "later".
