I don't know how old you are, and it's probabably a moot point, but it's easier for those of use that started playing in our teens. I don't remember being burdened with too many analytical thoughts at age 13. I do remember hitting wedges over the house with a wide open clubface. I pretty rapidly figured out that you can make hit a sandwedge chip shot with hook spin and with cut spin, etc. etc. But I'm the same guy that wanted short game included in my first lesson with Brian.
In my opinion, you don't have to set your short game goal at some unrealistically high point. My observations over the years clearly are that most players have terrible short game technique. They get the handle behind the ball and hit at it with their right hand. On the other hand, many get it up and down with great frequency in spite of the technique. I would think that you could be fine by just learning a basic chip and a basic pitch, but as with anything else in golf you have to practice doing whatever you are working on.
However, most people just hate to practice. The ones that do like to practice then have to find the time to practice and reality often times makes that impractical.
To me the fun in golf is working on techniques that might improve my scoring and working on correcting what went wrong over the last several rounds. I'll give you an example.
Prior to the lesson I had a string of chili-dips on short pitches. Frustration was an understatement. For 50 years, all my pitches and chips were played from an open stance. I never thought about it, but while this does sort of pre-open the hips, it promotes an outside take-away and a steeper angle of attack. Brian immediately got me to square up my stance, stop popping out, and hit it with my pivot. Instant improvement.
I also have been following very similar techniques in a book by another short game guru. After literally hours and hours of practice (more than 15 hours), it's starting to stick. You can get in the right positions and hit chip after chip in practice, but when you take it to the course, you have one chance. The successful crisp shots are coming more frequently and the chili's are mostly gone. My thoughts are less arm swing, and control the shot with acceleration from the pivot keeping weight forward over left leg.
