At what point did you go full-time?

Keen to hear about the decision process other indiehackers went through when making this judgement call.

Personally, I'm 22 months into a Phishing Simulation SaaS platform - https://caniphish.com/. Went GA about 6 months ago and crossed $1000 MRR a little over a month ago. The platform is continuing to grow and I'm wondering at what point I go full-time on it!
