I've had some good advise over the years, but me and few of the lads at work knocked up a list, feel free to add to and Highlight your own faviot
Learn to enjoy the good simple things in life without over-indulging - don't mix your drinks, there's no need.
Rely on yourself - you'll always be there. Try turning off your phone and computer for two whole days and see how you get on.
If you're not happy - find out why: what's making you unhappy? Change it. Job, partner, studies - there are always ways out and the simple act of doing something about it will make you happier.
Don't marry the person you want to be with - marry the one you can't be without.
When you think "I'll just have one more drink" - don't have it.
Go somewhere new, try new things, meet new people - especially while you're young.
If you love someone - tell them occasionally. If they are your parents/grandparents it is especially important.
If you're a bloke, buy flowers for your misses (or Mr) when they're not expecting it and don't get cross if they think you must have done something wrong - just tell them Che told you to do it.
If there is somthing in your life you love doing - try to find a job where they will pay you to do it.
Don't be afraid to ask for help from someone you trust; don't be afraid to give advice to someone you love.
Spend as much time as you can with your kids - blink and they're grown.
Steer clear of hard drugs.
Never show off when driving a car - don't be afraid of being called a sissy.
Men: agree with your woman and let them win arguments. If necessary - do the opposite after she's won.
Women: you'll be amazed how grateful a man can be if you put yourself out for him occasionally.
Gay men: use a condom.
Lesbians: have fun.
Singles: enjoy the peace and quiet. You'll find someone when the right person comes along (if that's what you want) - don't settle for second best, but remember: all relationships need give and take.
At work: do your best and don't stab others in the back. Bite your tongue but don't put up with shit. If you're really not happy, see above: leave.
