He traveled to 50+ countries and slept outside everywhere except poor countries where it was cheap to get a bed.
When he returned to the US, he sold cars and was homeless. Literally he slept outside but still worked out and ate well. When he got a car, he still slept outside.
He recently just made $60,000 driving for Lyft/Uber in 6 months and saved $30,000 (assuming a lot went to taxes).
He then moved and slept in hus car for 1+ month while having 30k and perfect credit, and still driving. Now he's taken a month off to pursue creative and side projects.
If you don't have a family, then anything is possible.
