I was lucky to be given/earnt some money before I was 21. Basically enough at the time to buy a mid range new car. I invested it into an Index Fund and didn't spend any of it, even when later I'd had 4 kids and times were tougher. 25 years later it has quadrupled in size and by the time I retire I am hopeful it will fund my entire retirement.
