I'm guessing you're into programming so pick a few languages and learn them in your spare time - http://stackoverflow.com/questions/194812/list-of-freely-ava...
For idea development, keep reading posts on HN, TechCrunch, GigaOM, VentureBeat, etc. Spend a few minutes daily writing down words / trends you notice for startup ideas / startups that are doing well and others that are doing bad. As you do this more and more, you'll start to notice really great trends, and you can iterate on them. Also for ideas, go through your day and write down every pain point on a sheet of paper (the writing part is important, typing it in isn't as useful!). As you build up both pain points and trends, you'll get the hang of mixing / mashing ideas!
I watch little TV or other ad-driven media. I was amazed, after a long absence, by a movie-preceding ad for macaroni and cheese. 90 seconds of big-screen viewing time, produced at a cost of millions of dollars for...cheap pasta and powdered cheese food? That's not ideas, that's not execution per se, that's sheer force of will. Ditto for cheap trinkets sold anywhere. Ditto for frigging Spongebob Squarepants. That's hiring an accountant and an ad director and filling in the blanks they give you.
As I wrote in the prior thread: pick something and do it. It's not about brilliant ideas or clever execution, it's being relentless.
Seriously though, it pales in comparison to its stylistic forefather Ren & Stimpy, but it's still a really solid show.
