I do know that with Avon, you have to work bl**dy hard to make anything worthwhile, although if you like the idea of selling then it's a doddle and very enjoyable.
But others have said it here - you need to have a good look at what skills and interests you have and then think of ways in which you can use them. Look at your hobbies, look back at any paid work you used to enjoy, or think about anything that other people say you're good at. For instance, I'm an ace pressie wrapper and people are always asking me to gift wrap stuff for them. It's not something I'd want to do for payment, but the potential is there. Also, a friend of mine, when her kids were younger, would buy up good second-hand toys cheaply and then resell them at a profit.
No matter how unimportant or trivial a skill something appears, it may be something you could use to make money. For every little thing you can do well, there's going to be someone out there who can't and who is willing to pay for someone else to do it.
Do you like gardening? What about selling home-grown fruit and veg? Can you arrange flowers? Make clothes? Paint & decorate? Play the piano? Mend bikes?
You just have to do a little creative thinking, that's all.
Good luck.
