Strengthening your shooting ability is getting out and shooting every day.  That's what I am doing.  More often than not, though, I am left dissatisfied or frustrated for any number of reasons both tangible and intangible.  A great New York photographer, Jay Maisel, refers to getting out daily as, "visual push ups."  He says with a smirk, "You are still going to be frustrated, but frustrated on another level."
