First thing's first, you've got the golf bug. Good! Next, you want to improve and know enough to ask for help. Also good.
As one that has been playing and working in the golf biz for over 30 years, I'll start by sharing this. There is no such thing as having the perfect game/swing/technique. Even the legends of professional golf, Tiger, Hogan, Nicklaus, etc.. would agree.
Rather, playing golf to the level one expects of themself, is part purposeful practice, mixed with positive thought and unwavering confidence.
Take a series of introductory lessons from a regarded teaching pro in your area. Watch the PGA Tour pros play on TV. Do some research about the greats of the past. Instead of tieing your brain in knots watching video after video, or reading countless magazine blurbs, compile your list of favorite professional players. If they've published an instructional book, read it. Again, don't follow the hype provided by the no-names your friend told you to watch on YouTube.
On an entirely different tangent, you're 29. Are you secure in your career? I switched my career path at 27, and took a job at a private golf course. With unlimited access to play, my game SKYROCKETED!
