I have a few on the to-do list, will echo a few of Baz's and Stephens....
In no particular order...
1. Quit smoking.
2. Eat Healthier.
3. Get onto the surfboard again.
4. De-clutter my life... come from a family of hoarders.
5. Take more risks... eg, the tough one, pluck up the courage to tell the girl at work I love her
6. Crash and burn (see #5)
