I'd say first have the desire & will power to self-host everything. The internet is a powerful resource to learn how to do most* things I mentioned. 

To get started I'd say do a search for what you want to do yourself like, "how do I run a local LLM?", etc. and go from there.  

 Thanks Super - we all need a kick in the ass! Time to GSD and keep steadily moving to self-hosting!
