Please take this as a compliment, but are you related to Rickey Henderson? You have a similar physique to his and a swing from a deep-crouched position similar to his. And, for those that aren't up to speed on his backround, his first love was football, not baseball.
But, back to golf.
I'm no expert, so take what I say with a big grain of salt. IMO, with the proper instructor, you'll have no problem shooting better scores just after 2 to 4 lessons.
First off, no relation to Ricky Henderson . However, growing up in northern California in the 80s and 90s as an Oakland A's fan, he was my favorite baseball player and I used to always try and emulate his batting stance. So maybe it's a bit of coincidence or maybe not. In fact, I even wore #24 all throughout high school & college football in part because of Ricky.
Second, thank you for going into detail with your post. I can relate to some of those things. Last year I probably played 2-4 rounds per week from April to July, whether it be 9 or 18 holes. This year, I'm always hesitant to go play or even go to the range because my mis-hits are so bad. I played one 18-hole round with my brother a few weeks ago and shot 100+. I didn't want to play again until I spent some time on the range after that. But my range sessions haven't been good, so it feels like a waste of time.
Even this week, it's been great weather, and I'm itching to go to the course to practice or play, and eventually I talk myself out of it due to not wanting to get frustrated by my play. So, needless to say I'm definitely going to get lessons, and I'm anxious to get started. I will start by taking a half-hour lesson from this instructor and see if I like him, and if I do I'll commit to further lessons. Being single and near 3 golf courses, I have plenty of time to practice until football season starts. I coach high school football and we have spring ball next week, but then don't start up our summer practices until June.
Thanks everybody for the input.
