The issue is that you're likely leaving too much on your inbox. I use my inbox as a to-do list (especially before Gmail removed inbox and its reminders, now I just create a draft with a title) but it doesn't contain the backlog of all the projects I'm working on.

If you have too many tasks that needs to be done I think you should group them by activity and store them in a separate place. Then you can timebox "dealing with $activity" where you just get down with those tasks.

Eventually you can hire someone and give them the task of a certain activity (which can be anything: a software project, dealing with a visa application, buying a house etc)
