Have you thought about whether this is kind of backward? It is possible that having a certain genetic predisposition makes it easy or difficult to stick to a good routine.

I see this in myself: No matter what I do I find it very difficult to stick to one routine day after day after day. I just kind of get extremely bored with it quickly. I know my life would probably me noticeably better with more routine, but I'm just not wired that way.

I do have a lot of creativity and a strong analytical mind, so maybe that's the price I have to pay for that.

Long story short: people are wired very differently from each other.
