There's a common denominator between all highly successful people - quitting is never an option, period!
Incredible things will happen in your life if you make a commitment to never EVER give up on your passions, no matter how long it takes or how much struggle is involved! I'm living proof that it can be done if you're willing to endure massive amounts of pain. I quit a lucrative career in order to pursue my passion. I went broke financially, emotionally, and as a husband ... but I knew "quit" couldn't be a part of my vocabulary and "stop" couldn't be a part of my vision.
It took time, but it all turned around. The minute I hit bottom, my passion was tested and motivation created. I made a conscious decision that my family was more important than the temporary pain I was feeling - I couldn't quit. I wouldn't quit.
When it's all said and done, you're being defined by your reaction to the difficulties in life, not by the success you attain. Create a 1% Mindset that refuses to stop, ignores failure, and is fueled by struggle. When you do this, you become unstoppable!
