Focus.
Focus is absolutely essential, and lack of focus is one of the largest things that holds people back. Sometimes it makes sense to go through unfocused periods and experiment a lot, but once you can get laser-focused on a single area, you can get immense amounts done on that.
So okay, let's say you get the focus epiphany and want to get there, but you've got 10 things going on.
Now what?
Well, you might want to let 7 or 8 of those 10 areas burn while you get only the most important handled and closed out.
It's unfortunate but true -- you can only work on one thing at the same time. If it'll take you 40 hours to automate, streamline, transition, or elegantly close down one area, that means you'll have to be putting those 40 hours into it and not something else to get it handled.
What's tempting to do is to spread the hours around -- 2 hours here, 1 hour there, 4 hours here, half an hour there -- which keeps it from anything getting too behind schedule, but doesn't do the process of systematically eliminating things from your focus.
Of course, mind things that will have serious consequences for others if you don't do them. And prioritize things where the consequences of letting it burn will be particularly bad.
But to really wrap things up and get on to next things, you're going to have to give enough attention to projects to make a real dent out of them, and then get your transitioning done. This probably requires letting a few of the lesser important things to stay on fire for longer than feels comfortable. Suck it up, do it, apologize liberally to people afterwards if necessary, and then be disciplined not to get over-bandwidth on projects going forwards. It seems to be the only way out of the unfocused too-much-going-on woods.
