That story about the minimum wage job guy is true. I have this friend with mad hustle. He comes to the states for 6 months, works pizza delivery, subleases all the rooms in a house he leases, makes money on rent every month, and doesn't spend a dim on anything, dumpster dives.
By the next summer he always has ten grand saved up, and goes off traveling for a few months. He has been doing this for like ten years.
He wears his clothes until they literally fall to pieces. He is my hero.
One time we were sailing, and he suggested we paddle to save money on fuel.
