Of course not. That is a dumb mindset to adopt towards gambling practice, as mathematically you can't win on long term. What happens is that marketing developers subverted that motivational and inspirational mindset, which was originally aimed towards general aspects of life, to gambling. Therefore, that mindset isn't wrong and unfeasible, it just depends towards what you are using it in your life.

If it's about your professional career, your personal development and evolution as individual, or any other personal objective which heavily depend on you to succeed, it's completely valid. However, when you apply it to gambling, it doesn't work, because gambling results don't depend on you, since it's random and on long run the casino has a numerical advantage against you.
