No joke, I once met a guy like this in an indie game developers meetup, and on top of that he was extremely vague about his idea because he told everyone he once managed to get a coder on board and “that rat wanted to take advantage of him and his idea”, literally.
Top 1 for me would be a strong backup mechanism, and by that I mean something that is tested. Currently I have restic in place but I don’t even know if in case of a disaster the backups are ok.
And considering my lack of time, I would be happy with just that.
