Fierce Freelancers

Hello fellow adspire friends! I've recently been testing the freelancing waters, and was wondering if anyone had any advice to give/wanted to hear any of my experience? I just recently started out as a way to be creative outside of work + supplement my income (all that avocado toast sure does get expensive). There's a lot to take in with pricing, retainers, contracts and all that good stuff and I'd love to learn more!
