I agree with Mr.Thumbs about your salary... damn dude, you can make more at McDonalds...
But that aside, you should keep SOME mainstream job with stability and benefits and then do this:
Increase your daily porn work to 4 hours by staying up late into the night after the family is in bed. If you can double (or better) your porn income from that level of effort, maybe you will convince your wife and yourself that you have something. Or maybe you'll just keep making 5-7k/month without doing anything past that....
