I've missed millions of shots before becoming a champion, I've waisted many evenings working before I knew that my one evening is worth 10 times less than my sons' evening spent apart.
I won't give bitter sweet list of my mistakes here.
But will share a good story.
Lesson worth 11.000 Euros to

Once I bought a lottery and threw my ticket away. One day they called me to say I won the main price - a brand new car.
