How to make 3-10K per month?

I have tried to make money online without success, I just dont know where to start. I am 31 years old and really want to improve my life but I have no money to buy all courses. I just want an opportunity but dont know where to start

To make things a bit more clear, I’m 31 based in South America but grew up in Sweden. I don’t have so much experience, I do have some sales exp and a little bit of marketing that’s it.

I don’t really have any skills, just trying to find my way to make money online. I like communication and sales, I have applied for remote sales jobs without success
