This sounds simplistic/naive, but have you ever tried just starting a project?

With every project I have an initial reluctance to start. But once I start I usually feel compelled to finish it (these are usually woodworking projects).

Just start. Choose something realistic. Make it consistent. Even just 20 minutes in the morning or evening.

And if you abandon whatever it is - maybe "it" wasn't for you, but you probably learned something. Now do something else.
