Where to get started.

I am a 31 year old non college graduate. I wanted to continue my career in agriculture but it is not looking to good. Ag economy is terrible.

I am a self taught computer geek. I have no formal education in it though.

Where should I start?
What fields should I look into?

I have done a little bit of everything from programming to network setup.

I am not a computer newbie by any means, I just need help to focus on a new direction. Any help would be appreciated.
