Even though there are signature campaigns that pay more than your job, I still wouldn't advise you of doing that. First of all, it will take you quite some time to actually achieve the rank needed to earn that kind of money (read 1+ year). 2nd, you never know what future brings and signature campaigns might be completele reomoved, or traffic on this forum might drop so much that it won't be interesting to advertisers anymore.

What I would suggest you to do is to edcuate yourself, learn new skills that will open you to a possibility of a better job, while being active on this forum so maybe one day you can earn some extra money from it.
