I was probably in the same position as you a couple weeks ago, but way before that I already made some K's from IM. Stuff dies out by time and you have to find a variety of other things that you can try yourself. Everybody told me that I should get a real life job, and give up everything since I wasn't making a lot of money a couple weeks back. They even told me that I was never going to succeed with IM. People who are saying that, listen - DO NOT want you to succeed because you may potentially be their competition. And well other people may be helpful enough to hit you up with actual and decent advice.
If you don't know what field you want to work towards, it's not that hard. People think that there's millions of traffic sources, there isn't. There's only a couple of decent ones out there. Blogging does take time, that is true, there's a lot more to blogging than you think too. I'd recommend you go on a searching spree on Google or wherever and research what field you would like to take part at. The internet world has everything you need to know to get started.
Good luck dude.
