A very important statement in there is that you like your current job. We carve up life into tidy categories, like career and retirement, that don't have to be so cleanly distinct from each other.

If you stop enjoying your job, to me, that's the time to ditch it and pursue the creative projects you also love.

Another thing that I noticed here is our cultural fixation on pursuing exactly what we value highest. That might not be your current job, but your job is also a social venture that's undertaken with other people and adding value to others still. It's fine for that to outweigh what you would choose in isolation.
