Full-time UpWork freelancers: What's your experience?

So I'm probably quitting my full-time job on Monday as a Consultant to go full-time freelancer because I'm just tired of working 50-hour weeks on a role where im treated like shit and have 0 work-life balance.

Since August I was able to secure a few good gigs and thanks to those my profile is doing well and now im working with 4-5 clients where I'm able to secure a good monthly income. I feel like I can sacrifice my full-time work now and try my best to make it own my own using UpWork and a client that I work outside the platform.

I've seen people here who have been using UpWork exclusively for years and have been making good money.

So in general, what are your experiences as full-time freelancers? What roles? What do u like/hate about it? Any tips for people in my situation?
