A reminder that what you fill your mind with will manifest through your actions, thoughts and behavior. Make sure the words you speak and the thoughts you think are good ones. You deserve the best so treat yourself like the best.
I'm not sure if I completely agree with this because you can be happy from being with other people, but I think I would agree more if this said positivity instead. Being happy is a very personal thing and it really has nothing to do with anyone else.
