Building up your habit is a long process, and it can’t be rushed. Don’t start off too big (i.e. start off spending 8 hours on a project in one day). I mean you can, but if it feels like a drag then you’re biting off more than you can chew. Prioritize on sustainability and consistency; otherwise you’ll unconsciously tell yourself that it’s too hard and set yourself up for failure.
EDIT 1: I realize the post is more about having feeling inspired/creative vs wanting to learn, so my thoughts may not be answering OP’s original question.
EDIT 2: I think a better way to frame the question is how to bring creative ideas to reality. If that’s the primary goal, building up the habit of trying to apply our ideas is IMO really important. Otherwise, ideas will just remain ideas.
