since you are not interested in doing bounty campaigns(which I think would be good since it is usually a waste of time), you can start your own service, I mean create a thread and offer a service/skills and ask to be paid in bitcoin. but if you don't have services/skills you can offer, you can build up your account and join a signature campaign in the future(which I would assume you are interested in). but before all that, it would be better to familiarize yourself with the forum. you can check out the links the members have shared for that.
