I didn't read the whole thread... only the initial post and a few subsequent comments, so I'm not sure what's been said already.
Ultimately what you want, is to make more money. Seems obvious, and I don't expect I'm telling you anything you don't know. However, it doesn't come without sacrifice or luck. So, if you want to make more money, you have a few options...
1. Go back to school
2. Get a job where you have to take a step back, but where you can ultimately build towards something bigger
3. Start you own business
The reality is, the things you find frustrating at 26, will make you miserable at 36 and 46. You're still young, and have plenty of time to right your course. Much like you wish someone would have impressed upon you the value of taking your late teens more seriously, now is the time to take your late twenties more seriously. Make a change, sacrifice, and get on the path you want to be on.
The only other option is, to learn to be happy with less. There have been a lot of stories in the news, especially with the downturn in the economy, about people carving out a life for themselves on very, very little money. However, I'm not sure you're that type of person. I know I'm not.
