I'm a loser and I want to change that - now

As for making progress on some goals, I'd check out the literature on deliberate practice, and the strategies on the Less Wrong and Overcoming Bias blogs. (Your note is displaying a range of cognitive biases.)

The recent book on Mastery by Robert Greene lays out a lot of tactics. The good and bad news for you is that almost all approaches to mastery require becoming more involved with other people. The Mixergy interview with Robert Greene is excellent. I don't remember ever hearing Andrew Warner as excited about a book. This interview is not behind the paywall yet, so enjoy it while you can:

Your life isn't going to get back on track until you start thinking better about yourself. The reason you're so self-absorbed right now is because you're constantly beating yourself up; its a full-time job. Once you can have a little self-esteem and equanimity again, its going to be a lot easier to think of others and work projects and be able to achieve your goals.

At the very least go on vacation, or move; its easier to get out of ruts if you're somewhere new and different, for neurological reasons. Go somewhere new and remake yourself closer to the person you want to be.

If you do nothing besides trying the same thing you've tried dozens or hundreds of times before, that's what's really worrying and dangerous. :-(

... as a system to translate those dreams and ideas into consistent actions over time. Dalio identifies some important, unavoidable choices that you must make to be successful;

1) Honest Self-Assessment versus evasion or rationalization. 2) Selfishness and your values versus Others and external expectations as the primary motivation of your actions. 3) Self Responsibity versus blaming others or wallowing in self pity. 4) Pro-Effort versus Anti-Effort, achievement is work. 5) Long range action and motivation versus short range mentality. 6) Adult versus a child's reaction to the inevitable frustrations of purposeful action over time.

Good Luck.
