Need a new start AGAIN

This is getting downright depressing. I sound like an addict.

So far today:

Exercise: about 15 min. this morning
Food: Had a smoothie and vitamin for breakfast, but didn't pack a lunch so things went downhill.
Sleep: I was doing better for a while, but the past 2 nights I've reverted to my bad habits and started staying up late for no good reason (internet or TV).
Work: I did hire a part-time assistant, which has been helpful for organization and dealing with the backlog of admin tasks and phone calls, and more of my files are getting up to date. However, there is still a major file to tackle, and I need to get on top of the billing/accounting again (after doing a blitz last month). I also feel like an idiot because I went to the wrong address for a meeting this morning.
