I must admit, that I have learned more from my negative experiences than I have ever learned from my positive one.
Positive belief in yourself will give you the energy needed to conquer the world and this belief is the power behind all creation.
Do the things you used to talk about doing but never did. Know when to let go and when to hold on tight. Stop rushing. Don't be intimidated to say it like it is. Stop apologizing all the time. Learn to say no, so your yes has some oomph. Spend time with the friends who lift you up, and cut loose the ones who bring you down. Stop giving your power away. Be more concerned with being interested than being interesting. Be old enough to appreciate your freedom, and young enough to enjoy it. Finally know who you are.
The difference between being mediocre and achieving excellence is you.
A failure is always in the passenger seat in his or her life.
