5 habits huh? Let's see, I'm so full of good and wonderful habits that it might be difficult to come up with 5 bad ones.
1. I'm told that I snore, I don't believe it though because I've never heard it.
2. I like desserts too much
3. I really should get more exercise.

I'm going to have to REALLY think about the rest, there are so few bad things that I do,or should that be do badly.

Do the habits have to be my own? Or are we talking habits in general?
