I'm no stranger to trying different rituals myself. In fact, I've read a lot of personal development. But I still find it hard to implement things for any length of time.

One of the lessons I've learned is keep things as simple as possible--simpler than you think is reasonable. For example, my bare morning ritual, which I stick to most of the time, is about 15 minutes, but makes my mornings far more pleasant. A second lesson that is 100% ingrained in me is to wait awhile before thinking something is a success.

It's so cool that another SLC LWer takes these things seriously - which is why you should help me put together an instrumental rationality subgroup.

EDIT: I didn't see that you stop yourself from changing the ritual more frequently than every two weeks. That's something I myself have trouble with--I kept wanting to update my rituals every few days for awhile, until recently, when i decided to just say heck with the rituals for now, I'll just start with something easier.
