Dear past me,
Some things I forgot in my previous letter:
When you go to Amy's 18th, do NOT talk to Richard. He will fuck up your life for several months.
Stay with your mum as much as possible in 2007, because things at home become really sour, and you'll miss her when things change in '08.
Keep hold of the friends you have at high school and college, 'cause they're some of the best you'll make and you'll miss them later.
Don't waste your time on the tall blonde colleague when you start at the games store, he's NOT interested. Same with your customer friend on Xbox Live. However, DO chat more/play more Guitar Hero with the bloke on the forum.
Whatever you do, don't pull out at the roundabout that night you're lent Spore. You'll know when I mean. Go back and wait for your sister instead.
2008 is a damn good year for you. Enjoy it to its maximum. Try not to get sick before you go to London 'cause it really dampens the otherwise awesome trip.
When all the crap kicks off at the end of '08, listen to blondie and not skinny. Skinny will lie to you, keep lying even when things get better, and betray you.
Do NOT, and I repeat, do NOT accept your friend's request to play some Fable 2 at 1am in the morning. You will oversleep, be late for work, and face your boss' wrath for months.
Other than that, stop being such a sad act in High School, be yourself in college, and start a friggin' design portfolio already. Don't cut your hair short when you're 15, it looks AWFUL, you looked like a ten-year-old boy. Seriously.
Love future you.
