Join a signature campaign,start trading,start lending BTC to people
You can also offer a service in the service section and get people pay you BTC for the exact service
Just try something,that's all
I think signature campaign is the most viable job here for individual who does not posses the skills which are in demand in the online world like programming. If you understand bitcoin it would be easy for you to join the campaign available here and it would help you to understand more on the necessary information you need to learn to start a most advance job like trading.
