For me I think I just learned to stop being hard on myself for not finishing. They're side projects, you don't owe anything to anyone. I've also found that as time has gone on, certain side projects have remained compelling to me even after getting burned out on them the first time. Some of them I've eventually gotten back to, gave up on again, and then gotten back to. Before long it becomes clear that it's not that I'm perpetually undisciplined and lack follow-through, it's more that I've made slow and steady progress on those projects over the years. Only other advice I can give is that when picking a side project, find something where the process is as enjoyable as the outcome.
