A fire needs air as much as fuel. Pack your schedule too tight and nothing catches.

Wood with no air around it does nothing but smoulder, and people assume the problem must be the fuel. Effort behaves the same way. A schedule with no gaps in it has no space for the thought to catch, so you work constantly and the thing you were working toward never quite ignites.

Find one gap in your week and protect it from being filled. Not an hour of scrolling, just time where nothing is scheduled and your mind is allowed to wander. That is where the ideas you are waiting for tend to turn up.
