be very honest with yourself about your current hourly rate before you leave. as a full time person, you mostly do things you already know how to do, and you may or may not 'work' every day. as a freelancer, you only get paid when you do work that delivers value

freelancing is total BS unless you're good at negotiating and have a deep network in the thing you're trying to do

it can also be valuable if you're trying to create influxes of cash every few months to break even on finances while taking a year off to start something

but it can also be an awful distraction that kills more momentum than it adds runway
