Make a list of things you want to do but don’t start it. Remove them when you lose interest. If anything stays it might be a goer. You will never have time to do everything. Also, think about what you really want to achieve. When you think “I’ll make a roguelike in X!” do you actually want to make something you or other people want to play? Or do you really want to just have a cursory understanding of how a roguelike works? Or to get a slight familiarity with language X? Do the initial research without committing too much to it and see if you maintain interest.
