It might be better to interpret in the context of the subtitle: “Advice for myself around leisure activities.”

If my advice is to myself, I don’t see how it is condescending. It seems by definition that it can’t be. I cannot pretend to be above me.

My summary of the sentiment would be “don’t allow the weight of imagined judgmental eyeballs to steal your joy in trying or pursuing your personal creative endeavour”

There is an irony in the blog now being seen at HN scale and judged.
