What are some practical online income paths for someone transitioning out of a long-term job?

I’m worried about potentially losing a long-term job and I’m trying to explore realistic online income options.

I have computer skills and some design experience, and I previously ran an Etsy store (which was permanently banned, so that route is closed). I posted some coloring books on KDP Amazon, but no success so far.

I’m not looking for “get rich quick” ideas – just legitimate ways people are actually earning money online today.

I’d really appreciate hearing what’s worked for others or what paths seem worth exploring.
