Sell accounts. Sell some software that is more than you claim. Niche down.
Don't sell copywriting or web design. Don't focus on services that 25 year student girls offer for peanuts.
Try to get into Fiverr ads. Think of it like a business, that is such a structure:
1. You pay them.
2. They give you leads.
3. You provide.
Nothing more. 3 steps. Simplify instead of complicating.
If it doesn't work, do something where you can yield $20 or so a day without big effort.
Then do it 5 times to make $100 a day. The key is to not obsess and cry over something that doesn't work.
Push your thought to projects than you can focus on for next 20 years.
Think more broad than just "freelance gigs". Try to find what you like and what is large, that is...
Maybe you like math and data? You can do machine learning training.
If you like ads, you can start playing with social media and become an expert of that.
If you like video and editing, give YouTube a go.
These are large websites and businesses yielding much more money than Fiverr gigs.
But be careful. Something like "content writing" or "web development" is really small compared to YouTube. It's also not gonna yield as much money as expert written content which isn't the same as general content writing - what I talked about before - "niche down".
