I didn't always develop this way, but I'm increasingly becoming convinced of the importance of vertical slices regardless of what you want to do with the game on release. I find it highly motivating to have a well polished representation of the final product, even if it's light on content, and it can help you discover those tricky development problems that inevitably come up earlier in the process. Plus, it gives you plenty to show off for marketing purposes and on a Steam page.
Just go make some games! Every project you complete will make you a little bit better at it.
