Here's an example of what I'm doing from the perspective of a person tinkering with a car:
I own a basic, plain, 1991 S10 pickup with 2.5l 4 cylinder. It drives ok except for the ocassional sputtering and white smoke when I start it. The window seals and hood vents have rust buildup. It doesn't have the best torque or speed, but gets me to work every day just fine. I can't floor it and jump into traffic, but it does ok for me.
(The golf relation: In 2009 and 2010, I owned a basic, plain golf swing. Nothing special about it. It got me around the course. I could drive the ball ok, except for the occassional push block or shank. The swing didnt have the best speed, but I had lots of fun playing with my foursome every weekend.)
S10 Pickup Overhaul: I was flipping channels one day and saw a show about overhauling trucks. One of the trucks on the show caught my eye. It was a rust bucket that looked like it hadn't been driven for years. They were replacing the heads, jettin the carb, adding custom wheels/tires, custom paint job, lowering it for better cornering performance, etc. I thought, hmmmmmm, nothing major is wrong with my truck the way it is, but I wonder if I can make a few changes to it and make it look different...maybe even perform better? What do I have to lose? If I blow the engine, I'll just drive my other car lol.
Golf Swing Overhaul: I was flipping youtube channels one day and saw some old black n white footage of a dude in a white hat. The swing looked unlike any other that I had ever seen. I said, hmmmmm, nothing major is wrong with my swing, but I wonder if I can learn how to do that type of swing? What do I have to lose? If I can't learn this new swing, I'll just go back to swinging like I always did lol.
S10 Pickup Overhaul: So I begin the process of tearing down my truck. While I'm rebuilding the engine and adding parts, I willl take it out for a drive to see how it was performing based on the things I had changed. I put a new carb in it...take it out and noticed that it had better gas pedal response, but it sputtered at high speeds. So I would take it back into the garage and tweek the carb some more. I also notice that when it came time to slam on the brakes and slow the thing down, it didn't stop as it should. More tweeking.
Golf Swing Overhaul: As I am in the process of overhauling my swing, I will take it out to the range or course to see what it is doing. I will do this weekly. I will analyze my movement as well as performance. When I see that my impact it fat and steep, I will just make a note in my journal with a date stamp so I can look back and see how I changed.....or didn't change, but I won't focus on fixing the impact issue because I'm still overhauling the swing.
S10 Pickup Overhaul: As the overhaul is complete and the engine is humming, I might get the urge to put it in a race. Will I be able to drive it to Talladega and enter it into a NASCAR event? Definitely not, but I can take it to any local track on a Friday nite, spin the tires and have a blast of a time, and maybe even take a few pink slips? Yep!
Golf Swing Overhaul: As the swing rebuilding is complete and the impact and ball flight is solid and predictable, I might get the urge to enter a tournament. Will I be able to put on my Foot Joys and take my persimmons to the US Open? Nope, but I can take them to any local course and have a blast of a time from the white tees, and maybe even win a trophy or two? Yep!
