Set firm boundaries in your life, and don't let others cross them, no matter how persuasive they are.
Fool me once, I'm the fool. Fool me twice and you're the fool. You don't get a third chance unless you demonstrate positive changes.
Don't outsource your self-esteem and self-image to other people and other things. Take the time to know yourself; a the end of the day, you are the only person inside your head. Make sure you are comfortable with that person.
If it sounds too good to be true, or too crazy to be true, it probably is.
Never let fear rule your life. Learn how to face your fears, because nobody else will do it for you. Fear kills relationships. Fear kills happiness. Fear kills opportunity. Fear can kill you.
Truly loving someone means that you care about their personal happiness. At the same time, it doesn't mean sacrificing yourself on their personal altar. Balance is always the key.
When you are in a relationship, the other person should always be more important than anyone else - except for yourself. If you don't take care of yourself, you will have nothing to give to the other person.
Be open about your intentions. Nothing destroys trust faster than acting in a supicious manner. If a friend or loved one asks for information, don't hesitate to give it. After all, you'd like them to keep trusting you. Doubt is a relationship killer.
If you can't trust yourself, you can't trust anyone...and if you can't trust yourself, how can you expect anyone else to trust you?
While there are more than enough people out there who relish treating others badly, don't automatically assume your friends and family are among them. If enough people keep telling you the same things, it's time to take a good, hard look.
If you keep failing, look to yourself. Examine how you treat yourself and feel about yourself. Most of the time, consistent failure is a sign of a self-sabotaging attitude.
Don't take things personally. It's not always about you.
Don't sweat the small stuff. If it won't matter in 100 years, then it's small.
Don't be afraid to ask for help. It takes strength to admit that you need it.
Don't be a Sunshine Nazi. It isn't always good. People aren't always in the best of moods. Deal with it.
It's okay to have your feelings, just be careful how you express them.
It's okay to not be politically correct.
Never let anyone or anything abuse you. Nobody deserves abuse.
