Start small. I've heard that for years but never followed that advice until few months ago when I found MB and saw how the indie ttrpg community works. I was always working on "my next major groundbreaking project" and they all ended up the same way - in my drawer. I thought that small has to mean simplified and lame, which is not always true. Browse through your ideas and find the one that you still consider cool but will fit on one a5 page. Then work on it and publish it.

That's what I've started to do, so many half-finished Evernote projects that I increasingly got intimidated by because I've no idea how to do layouts, or draw, or edit haha. I've got just enough to submit to a Jam now. I think that's my start, I'm hoping to maybe do a couple more Folklore monsters and creatures and maybe I can successfully cobble them together into a little booklet :)
