I have a plan but don't know if it's profitable

Become a bus/van drivers for school kids/students
- Get a PSV license -> which is a must
- Apply for class E license -> if you plan to drive a big school bus, else it's just PSV license with D license for regular school van (if I'm not wrong)

since you will have plenty of time when you are old so might as well train yourself to drive a van/bus, just make sure you fetch the kids and drop them off to school on time every morning + afternoon +/- evening

Exercise and eat healthy

I know a guy at 37yo already got type 2 diabetics, high blood pressure due to excessive smoking

I know another guy at 55yo, perfect scores, heart pressure macam marathon runner, because he exercises.
