What works for me is a step I find most people like to skip and that's planning. As a number of other folks have said, if you have small things then you're more likely to get them done. Often though you'll need a bunch of these smaller things to make a product that someone might be worth paying for. So what I do is I plan the project out into modules or blocks of functions that take a few days at most. I know for myself I take great pleasure in crossing things off lists (this is literal, I write things down in a TODO and physically cross them out). To me it's satisfying to see the list get smaller. Seeing the list get smaller, and knowing there is an end, keeps me motivated. Now I still have moments where it can feel like a grind, the worst seems to be when something is just over half done. That's when it's the most important for me to tell myself, well I'll just work on this one thing and I grind through it. Then when I'm about 80% there, that's when a lot of motivation comes back to finish it. Hope this helps.
