Limits

If you always put limits on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.

(Bruce Lee, Martial Arts Expert, Actor and philosopher)

Always have the utmost confidence in what you do. There is a saying that goes "the sky is the limit" however, I say go beyond the sky because all things are possible with belief, sacrifice and persistence. There are no limits if you believe in yourself.
