I have been actively coding for the last 7 years and somehow I still don't know how to freelance. I find it such a hustle sometimes. I have tried a few times in the past and if it's not a shitty pay to no pay, it's a shitty client or an absurdly old angular 1 project that needs support and additional features, WHYY!! just WHY!!

I want to give freelancing another chance. Help!!
How and where can I freelance properly? Tips and pointers are also welcomed.
