Well... It reads like you are talking about side projects? The big question is: Are you happy with what you are doing when you are doing it? Do you expect yourself to produce sth. at the end of this cycle? Or are you putting yourself under pressure, because "others succeed, and so I have, too"? Sometimes, it helps to free your mind and your thoughts just by doing something completely unrelated to your daily routine (read: daily job). If you are at the 25-50% stage, personally I don't think there is something bad at just dropping it, and look for new challenges. At the end, it's your free time, and it's completely yours to decide what you are doing with it. Maybe, at some point in time, there will be "this one thing" which you will stick to, because it makes your heart feel happy in the long term. And if not, that's totally fine, as long as you had fun on the journey. Just don't put the "I have to do finish it!" pressure on you - as you already noticed, you don't work like that. Oth, if you are unhappy: Think about smaller scale projects. Obviously, you cannot stay focused for a long time. So, you might want to pick smaller projects. Don't talk yourself little. Find something you can finish in, let's say, two months or something. A project that better suits a smaller attention span.
