That's a pretty high-level question. I'm only maybe 30-35% of the way on my journey, but I hear what you're saying. When I'm feeling highly motivated, but there are no "big things" to accomplish at the moment, or any major milestone s in the near future, I try to do one of two things: either knock out some prep work that might help me down the road, or try to do whatever it is I will do in FI.
So, as an example, when our life gets busy, housework slides. And when housework slides, we eat out more, which delays our journey. So, I keep a list of "sometimes" chores to tackle when I'm feeling motivated (like, prepping freezer meals, organizing cupboards, deep cleaning, etc.) that I can fall back on if life starts to get too crazy. Or, I plan on writing more in FI than I do now. So, I might sit down and outline chapters or brainstorm character ideas. Even though it is a little frustrating to only have a few minutes to work on it, I feel like I'm kind of "practicing" FI by doing those things now as much as time will allow now.
I don't know if that's the direction you were thinking, but I hope that helps.
