There have been so many times where I've paused, wondering if I should "snooze" rather than get up, then remembered that I don't hit the snooze button. I get up in 10 seconds or less.
I've written about this before, in "How to Do", but I feel it bears repeating. Rules have saved me from apathy, depression, obesity, and probably a bunch of other things, too.
We are what we habitually do, we habitually do that which we are, and we are what rules we have decreed.
You don't "try not to smoke" if you're a non-smoker. You don't "try not to rob a bank" if you're not a criminal. We simply do that which we are. We are not a smoker, so we don't smoke.
I always do what the guy who makes my schedule tells me to do. He's a hardass, and sometimes I don't want to, but it's my job to listen to him. The fact that he's me doesn't matter. It's a rule.
I get up in 10 seconds or less. It's a rule.
I don't hit (or even have) snooze. It's a rule.
Over time, our habits forge our identities, and our results. I strongly suggest you take great care in designing a life by deciding on the rules and habits of one.
