Same as any other skill, like drawing, or physical feat, and the progression is much slower than most IMHO. It always feels like you are getting nowhere, but at some point, you'll marvel at how far you've come.

That said, also be aware that meditation isn't the panacea that it's often made out to be. It certainly sounds like it's what you are looking for at this moment, particularly since you mention that you 'can't meditate'.
