2) Health is the best wealth, don't let poverty put you down.
Well, not necessarily such a good piece of advice for those too poor to maintain good health...
Anyways, my advice is a good one I think:
Don't put off till tomorrow, what can be put off till the day after tomorrow.
I also have a few more for ya:
If life gives you lemons, say "Sorry life, I didn't ask for lemons. I asked for a speedboat"
Never bother with love, cause we all either die or leave each other in the end anyway, and what makes you happy will make you twice as sad
If you're scared of STDs, remember to only reuse a condom three times
Stop trying hard at school - Everyone's always told to do their best and get good grades, but we need unskilled and uneducated workers to do the grunt jobs nobody else want.
Narcotics may ruin your life, but if you're so far gone into a dream world you never notice, is it really so bad?
And finally, and perhaps most importantly! Don't always listen to some stranger on a forum telling you what to do, be a bit critical about what you hear - it may be good advice, or it may be bollocks - Learn to sort things out.
