Always be a first-rate version of yourself instead of a second-rate of someone else.
- Judy Garland
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort.
- Herm Albright
You should always just be yourself, if you have to be a certain way for someone else to like you, they ain't worth the effort of changing. Be honest with yourself and everybody around you and you will find people that will love you for who you are and not try nor want to change you.
Regardless of the circumstances things will always get better, unless you just give up and let the bad hang around. The best first step to making the bad leave your life is to have a positive attitude. No matter what, you still have your life.
