I noticed that, as I get older, I tend to have less time, and so I try to optimize my time. When you don't have an hour a day to work on your side project, but 15 minutes a week, then you do what is needed for it to start working, even if it's not perfect or far from what you wanted. If you have plenty of time try to make the smallest thing that does approximately what you want. Then iterate over it, but always small but fully functional incremental changes. Don't be afraid of having to throw it away, no need to get it right the first time.
