It all depends if you were driven to earn money. At 27 years old I did 50 hours between 2 jobs, by 19 I did 200 hours weekly up to 110. No personal life, just work, shower, eat, nap then change for next job. I remember sleeping in my car to catch a few hours brtween jobs.
I always needed money, helped my dad, myself, saved for my house and to buy a new car. Once I was 22 I cut down to 60 hours a week, decided working two to three jobs was insane. Missed the money.
