As someone who is seriously considering leaving a job with a salary in the upper 10% of software developers in my city (over 15x what you are paid), plus benefits and who doesn't, as of yet, generate any side income. I'd say that your "risk" of leaving the job seems very low to me. If I were in your position, it'd be a no-brainer.

I understand this is all relative to your point of view, but just wanted to give you someone else's perspective.
