(there's a typo in my post: "the ones who don't a solution and get out of the problem" ought to be "the ones who find a solution and get out of the problem")
> I'm not so sure about that. Mind you, I had already been thinking that putting some effort in limited amount of time instead of doing nothing at all before reading the article, so if anything the latter gave me some more confidence that it's actually a solution that at least worked for someone
Yes, absolutely, but for the kind of people I'm talking about, it's like telling an overweight person to "just go to the gym, bro". It works, yeah, but there's some who do buckle up and go to the gym, and there's others who stay stuck in a cycle and don't take any steps out even thought from the outside, what they have to do is obvious (for example, some cope with stress or anxiety by eating. How can they become healthier without tackling the root of the issue, which is the source of the stress/anxiety? This is what I mean by things having emotional causes)
For ADHD, you needn't look too far. There's a top comment in this thread about someone who spent 40 years with these issues until they got actual help. Once the root is identified (diagnosed) then the difficulty in dealing with the problem goes down.

> Actually even better, was it that for you?
It's good that you ask this, because I don't know your situation. As for me, I basically tried to exhaust the possibilities by reading self help books, then moving into philosophy (mostly eastern) and then moving into psychology (via Jung's books, and Alok Kanojia's youtube videos). No tip or trick helped me, and intellectually, I knew what the right answer was all along (an equivalent of "just go to the gym"). But that still didn't translate to action, which surprised me. In the end, I was forced to leave my overly intellectual/rational view of the world, and delve into what Jung called Eros, a contrast of Logos. But don't be distracted by the name. Perhaps it's better to talk about "intelligence quotient" (IQ) and "emotional quotient" (EQ). My underdeveloped EQ was causing me quite a bit of problems, because I wasn't aware of my emotions, of what I was feeling, of why I moved towards some things and not towards others. EQ is related to motivation, among other things. That's where what I wrote in the DIY path comes in. It took me a year of work. And it taught me a very interesting meta-lesson: I noticed in hindsight the amount of effort that I had put into this problem. It made me feel so desperate that I spent hours and hours going through books, taking notes every day, and learning a lot. But for the areas that really mattered to me, I had been led away. The lesson is that the more intellectually important something is to me, the harder it becomes to deal with it. This can manifest as perfectionisn. For example, I don't care at all about how my books are arranged in my bookshelf. So I place them as they fit. But if I care a lot about organization, I may keep them in boxes for years while I fret over the best way to implement the Dewey system for my 1000+ books and also planning (but not writing!) an app to scan my books into a local database and so on.
(What do I mean by "intellectually important"? It's whatever we aren't led to by our emotions yet still matters to us. When I was led by the emotion of despair, I studied ceaselessly to get rid of it. But when I think about wanting to do something without a strong emotion backing it, it's harder to jump into it without forcing yourself)
So I care about a lot of things, and I care a lot. Also, I want to work on everything.
So my inaction here was because I was scared of the possibility of letting go of the others if I dedicate myself to a few things, and truly focused on them, devoting my time and energy to that endeavour.
That's what annoyed me when I saw others, who spent years on making their passion project (whether a game, a set of paintings, a program or a tool to help others, a web novel they self-published, or whatever else)... And I knew what I had to do. Do what they did but for what I care about, for my ideas that I feel so strongly about. And I wasn't doing it. It's fucking annoying, like trying to lift your hand (which you know works perfectly) but you can't.
As for your case, only you can find out. The first link that therapists will try to find inside you is trauma, because that kind of stuff has far-reaching consequences on everything in your life, including motivation. But it's not always trauma, so don't think that there must have been something suppressed inside you or whatever.
For example, I had a lot of problems from having been a "gifted kid", being treated like I'm super smart and whatnot. That pushed me away from hard work and from things that weren't immediately easy, and that a big root cause. But it wasn't a trauma of any kind - I had a normal childhood
About my progress... I'm working on it and getting much better. I recently passed a big exam, and I'm honing some of my skills, putting in the hard work.
Good luck on your path
