I only "finished" 2 projects yet.

Before that, i only started them and lost motivation after ~2 weeks. The projects a wanted to do were cyclic though, so i often came back to restart things i had left unfinished.

It took me time to change that, but the main thing i did was starting with extremely limited projects, that i knew i could finish in 2 weeks. I did very basic things at the beginning, like hosting a pure html website (but it was by first website i hosted, with nginx and certbot). Sometimes i would get back to it and improve something, like styling, text, SEO,...

I say "finished" because the bottleneck is finding users, not the code. So i still work on these projects, but not at the same speed.
