Hire a part-time project manager.
A good project manager is immensely helpful in (1) teasing out and decoupling requirements, (2) producing a work-breakdown structure (WBS), (3) setting a schedule/timeline for execution, (4) assessing risks, and finally (5) controlling activity and adherence to the schedule.
These are all activities that suck to do alone. A project manager offers a useful organizer and controller. Basically, they represent a forcing function.
Just like personal trainers help unmotivated people stay in-shape, I think a personal part-time project manager would help you follow through on your projects.
If it were a business, these would probably be your customers, you usually reach out to them via sales. If instead these are ideas (software) that you want to explore, open-source is a great avenue. As you gain users, issues filed for new features or against bugs become your motivation. To gain users in OSS, you generally need to publicize through a blog or something.

Just find users, and they’ll do it organically.
That is literally the job of a CEO. He executes.
People argue that money is never as good a motivator as true passion is. I am not taking sides on that matter, it is just something to consider.
I think it's a little weird but workable, I have at one time worked with someone who had a quite similar disposition (he was more of a product and sales guy) and he literally hired a managing director for his newly founded company so he could do the stuff he was best at — on the topic he chose himself, in the company he founded himself.
