A thing I’ve been doing in my journal is what I call a “kickoff entry”. If I take on a new thing, or add something to my routine, I’ll write a little blurb about what, why, goals, and some thoughts about what conditions I may decide to end the experiment.
These really help to solidify the intent around the action, and help me be realistic about what I want to get out of it. Also, as someone who frequently jumps from one new thing to the next, it helps me pace myself a bit. If I sit down and write an entry, I get an opportunity to ask “do I really want this?” And “what am I sacrificing to make this happen.
I have a tendency to be very “oh this is going to be awesome!” And 3 weeks later have totally forgotten about things. This has been helping with that, some. It’s definitely fun, at the very least!
