Congrats on making that happen, my man...
I recommend a book called, "The Subtle Art of Not Giving a F*ck".
Women are great motivators whether they're coming into your life or leaving.
Motivation is a like a fart in the wind. It comes and goes. Dedication is what will get you to your goal (Klitschko).
What's your real goal, is it really yours, if still unsure read, "The Subtle Art of Not Giving a F*ck".
