I can relate to ABSOLUTELY everything you just wrote; I'm the same.
My mind is SO hyper, I've got loads of interests, hobbies, passions, plans, goals - a pretty lot of a lot of things and being nowhere near of how I dream myself to be, gets me in that point of inertia, procrastinating feeling unhappy and unsuccesful for nor being that but ALSO not doing any of that.
Recently, talking to my therapists, we got to the conclusion of me procrastinating because my lists of things to do AND TO BE is so large, and I feel so not even near of the start that I, simply, don't ever start. I feel uncapable. What I've been doing lately is using a Pomodoro app and it has helped lots with my hyper-also-unproductive state of my mind. Even though, at the start, 25 min of continous work seemed impossible.
But I also relate to getting so sick and done of the same routine everyday so I try to get free days every two or three days but I still get bored or tired of the routines I made because they made me happy. I don't know, people like us need to be changing all the time because of that. Maybe it's more like a lifestyle hahah
