There are 2 kinds of focus I try to keep: "short term focus" for tasks that must do done now and continuously for at most few hours and "long term focus" that is basically like building habits. To improve short term focus, I exercise with pleasurable tasks which require dedication and concentration. It can't be video-games or anything that promote a dopamine rush. It must be something that I have to do with attention and concentration for a time and feel the benefits only after I finish it. My favorites for this are playing guitar (classic guitar, pop guitar does not requires the same level of concentration or dedication) and reading a book. Sometimes I go out for a walk just to free my mind. To improve long term focus I try to avoid addicting behaviors, like when I turn on the computer and I have to resist the urge to browse the web or read unrelated news (or wikipedia rabbit holes) instead of working. I do like the AA guys, when I fell the urge to procrastinate, I think: "Just for today", like in "Just for today I won't browse the web before reading and answering my e-mails." The day after, I just think: "one day at a time" and simply do the same again. From what you suggest, it looks like you need focus to complete interesting projects. My technique for this is: start with the hardest part: if it is really hard and boring you'll probably abandon it without investing too much time. On the other hand, if you complete the hardest part, you'll have a very good reason not to abandon the project: the hardest part is already done! Sometimes I give up in the middle of a project because it is taking too long... try a smaller project the next time. Sometimes I quit a project because it is too complex... try a simpler project next time. You want big and complex projects? Break it in smaller simpler projects that are easy and fun to complete.
