I say why bother. I'm much too lazy to follow through with them anyway. but in the spirit of good fun, the following is a few that come to mind.
1. Eat more cheese
2. Stop touching myself in an impure manner so often
3. Put a quarter in a jar for every cigarette I smoke to make me realize how much money I'm wasting on them (which I'll end up using to buy more cigarettes)
4. Stop making improper advances at co-workers
5. Take a shower(and actually use soap)
6. Cut down on my bean intake (this one's for my family)
7. Stop wasting time thinking of resolutions I'll never follow through with
