Goddamn, thats a good answer, bluefeet.
It's going to be hard to make a quality, content-filled post after bluefeet here, but here are my 2 cents:
Don't be discouraged by how you see people doing here on 2+2. When bluefeet says "put your opponents on a range and check the HH to see how you did," he's talking of a process that takes serious time. These finer, delicate points of the game are tremendously hard to master, so don't beat yourself up if you're still unable to predict his range correctly most of the time after just a couple of weeks.
Don't measure your progress in time units, it'll only cause feelings of stagnation, boredom, hopelessness.
But its good that you've decided to improve your game.
Now use that search function, find old (and even older) posts, try to contribute in hand discussions.
Here are 2 examples of interesting threads that I have on my laptop (I have a gigantic folder of 2+2 links on my main machine, but unfortunately its packed up and ready to be shipped overseas right now).
