There were periods of my life when a lot of people didn't believe in me. I still had faith in myself. I really had to ask myself life questions. Where do I see myself in five years? Create a ladder for yourself and walk up the steps. Climb that ladder.
I had a very famous trainer tell me once 'You can usually train a wild animal but never tame a wild animal ever.' They are always going to be wild no matter what anybody says.
