Old stuff from my real journal
Do what you like. This can be two-fold. Firstly, don't do things just because someone else wants you to. If you don't want to do it, then don't. You are in charge of your own life and are responsible for your own happiness. Secondly, don't hold back from the things you do want to do. As long as you do not interfere with the rights of anyone else, there is no reason to keep yourself from the things you enjoy.
Be kind. And do it not for reward or gain, but to make yourself and everything around better. Do kindness for the sake of kindness. The gratitude from the people around you will be reward enough.
Be humble. People don't like to hear you ramble on about yourself; give them a chance to talk, and it will be for the better. Just keep your ego in check. Compliments from others are so much more satisfactory. Just make sure they have a reason to give you praise and you shall receive it.
