Methods of achieving progress in life with Attention Deficit

I don't know how many people on here also suffer from ADHD or any other neurodivergent disorder, but for me myself I find myself stuck in a loop of wanting to create and express myself in intense forms of any type of art like writing or drawing or music and whatnot, only to hit a dead stop in motivation/drive somewhere along the line. Throughout my life I've never been able to complete any large and long-scale self-driven project, and the ones that I was forced to do, like with school, were done so with heavy turmoil and with a disappointing result.

I've found that, with myself, the only projects I've completed that I'm proud of are the ones that I did in a short time frame, like just one afternoon or something, because by the next day I'm just completely out of it. 

Caffeine and Music usually generate a significant amount of energy to do something creative nowadays, and I feel like it hasn't always been this hard to push myself, but I don't know. 

If anyone has similar feelings of burnout and loss of drive, how do you deal with this? What methods are efficient, if thats how this works? I want to live a life of art and expression but I feel like I can't even do that most of the time because it seems impossible to ever pick one thing and stick to it.
