3 things I think are essential in a Profession: Motivation, Passion and Humility.
1) If the motivation that drives you is to become a guru of success and full of money you have already lost at the start ... what? the ability to enjoy life!
2) The Love for what we do enthusiasms each step of our growth and encourages us to improve ourselves beyond our limits ... winning in!
3) The presumption and arrogance are a prison in solitude ... There is a great teacher in each and every one is vital!
