Can I make money with a podcast and blog? Internet marketing?

I have a podcast and blog (linked together).

I have 300 subscribers and 1,000 visitors per day.

I sell ad space, sell my own ebook, and want to create a training program and sell ad space on my podcast.

I now only post 2 times per month but numbers stay constant.

I’ve been at it for 2 yrs, but I slowed down cause all I can make is $60 per month. I felt like it was too much work for that kind of money.

I’m now getting the itch to start up again simply because I love doing it… but given this picture can I possibly grow this into something that makes at least $500 per month?

My wife wants me to quit doing it all together even though I spend plenty of time with the fam, I guess I feel like if I made a little money she would shut up about it.
