I have developed a ton of skills since I set out on the mission of becoming a full time author. I can now code (at a basic level), do graphic design (intermediate), build websites (intermediate), manage distribution (advanced), do book formatting (advanced), write in a wide varieties of styles & genres (expert), manage social media (advanced), edit (advanced), build marketing and business strategies (advanced), and a wide range of other things. The tough part is figuring out how to apply said skills in a way that actually enables me to make money.
It reminds me of something we used to say when I worked in theatre. A techie without an actor is a contractor, an electrician, or a handyman. An actor without techies is a guy trying to emote on stage, naked in the dark. Lol.
