Home based/internet based job

Im 29 years old man from Estonia and I don´t have any profession or trade. I like my freedom and I enjoy traveling so I couldn`t handle typical 9-5 office job or anything what would limit my freedom. My question is can anybody recommend me a internet based occupation or a type of jobs I could do with my computer so it wouldn`t matter which side of the world I physically am and which would provide enough money to travel.

Thanks to everybody who take time to answer!
