Let's see:
1. Don't give up on playing a sport just because you are not instantly awesome at it. Any skill requires practise!
2. When you hit 21 start going to the gym rather than waiting until you're 23.
3. You're going to be given 25grand when you hit 18. Do me a favour & save 3grand of it.
4. Those things that secretly really bother you, you should probably go talk to Mum & Dad about them now because in 3 years it becomes a serious issue.
5. Do at least 1 science subject for your Leaving Cert & at least 2 more honours level subjects.
6. You're going to meet a girl named Sarah, you probably shouldn't let that get past hello
7. Take more photographs of yourself & Buddy (my recently deceased dog).
8. Leave Vodka alone!
