I’ve tried freelancing a few times, I never manage to make it work. The clients I find all end up paying less than a “normal” job so I end up going back to that. I’m working as a Solutions Engineer now. Its basically freelancing without sourcing customers and a consistently big pay cheque every month. Any tips on starting freelancing?
