I'd also say to don't retire cold turkey. Try to work part time for about a year if possible. That way you have one foot on each side of the fence. That way you can compare the ground on both sides.
The best I can say for the younger generation is prepare yourself. If you can't afford to live from week to week when you're working don't expect waiting for a cheque at the end of the month with forty extra hours of spare time a week to be easy. Start saving money now.
Remember yesterday, respect tomorrow, live for today.
Hug a tree, it's bark is worse than it's bite.
