Yep, a fairly well-known technique, albeit with a different implementation.
I would be more intrigued, though, to learn how to discipline your mind to do a task when it needs to be done (right now or at some later specific time). It seems that would take a lot more mental fortitude.
Example: I should get gas in my car on the way home from work. I don't need to, but it would help. A few hours later.. eh, I'm hungry, I'll get gas in the morning. Next day, late for work because I had to get gas. How do I discipline my mind to get gas when I should have? Silly example, but it's what came to mind first.
One idea is to train yourself to be aware of the fact that even though you may not feel like doing something, you can decide to do it regardless of your feelings. Taking your example, you could have said, I'm hungry but I'm going to get gas first.
