Sorry if my answer overlaps a lot with others, I didn't bother reading all of them. I have a similar personality trait. I have grown up observing this trait around me, and I think I manage it pretty well. The best way to control an attention that gets caught from one thing to another is to try to build some habits that may give the necessary structure. If I were to give a few advises: * Recognize that you are already starting some things and cut yourself some slack. A lot of people do not start things on their own, and even an unfinished project taught you things, the younger you are the more relevant this is. * Understand how hard it is to finish thing. Having a clear idea about an article for my blog takes me five minutes, finishing it ranges from three hours to two days of work: redaction, proof reading, picking an illustration and all... And this is just an article, if you plan to release anything open source. Adding a decent documentation, packaging it, making sure that the architecture does not only fit a personal need, it's nothing fractional. * When you have an interesting idea you often feel compelled to "serve it". In order to not have this frustrating feeling to let it down I have a simple wiki page where I add all my ideas, one after another, with a date. I know it's there and I can come back to it one day. * Have a very high respect of yourself. Whatever you are showing online should have some degree of completion. I am strongly against "oh this was a quick idea I had" public github repositories. Whatever it is I put online, I am thinking that some people are going to judge me viewing only this side of what I did. I impose myself some level of standards. * Pick your battles. Know that you will be able to commit to two or three ideas a year, maybe keep a list of what you have achieved what idea was on your top list and what ideas you actually went through. I try to do a monthly follow up on those. * Follow up. Linked with the above but probably the hardest to put in place. Take the time to have regular meetings with yourself, this enables two things: realizing that you have actually done things (see first point), and review your idea to kind of revive the almost dead one that you find interesting.
