Some people were in debt and they took the paramount and stupid risk of starting a company and it paid off for them with huge returns. Congrats you pointed out some lottery winners.

What should also be mentioned are founders who go into even grater debt and destroy there lives attempting to create companies when they are not financially stable. Get your self in an position where failing won't ruin your life (like worst case scenario you end up back in your moms basement) but seriously, if you are in hundreds of thousands of dollars in debt, statistically a startup will ruin your life.
