Building the indie hacker curriculum

hey makers, I'm trying to aggregate a comprehensive list of everything an indie hacker/maker needs to know in order for them to launch products within weeks instead of months.

Here is a list of categories I came up with, if you can think of more please share them and if you feel like you can break down a category then please do so!

1. development (frontend / backend / databases..etc.)
2. marketing (SEO / paid ads / viral / affiliate...etc.)
3. design
4. copywriting
5. product discovery/validation (problem definition / customer interviews / defining and running experiments..etc.)

feel free to share your own list or build on top of my not well thought out one!
