If lessons from an instructor were not available, I might suggest a visit to the local library, or internect connection, and read up on the basics of the swing. Address position, grip, and a one piece take away to the top of the swing. I wouldn't worry about anything else, untill I had a working understanding of those three items.
Once I understood the above items, I would move on the more finer points of the golf swing, a little at the time.
Too many times I think golfers over load themselves with swing mechanics, with out fully understanding these mechanics, and how they relate to each other. Frustration sets in, and they don't improve, or worse yet they quit.
Sometimes, it takes a guy a couple of years to find his game again after winning one or more majors. After a major win, I've heard they go on so many paid exhibitions and travel so much doing so that it wears them out, and can affect their swing.
But Jordan's worked on his swing over the last year; and it could be he needs another set of eyes, or a consultant to assist his instructor.
You are not yet 40, so yes you can definitely get more distance. But, it will come down to a couple physical factors: flexibility, muscle control, muscle speed, and coordination. It sounds like you have some coordination and control, you just have to learn how to properly let the club head go and know how to create ideal launch conditions. A pro can certainly help.
You don't have to be fred couples or john daly to hit the ball long. At 8 months, you most likely don't fully trust the swing yet. Once, you start trusting yourself more, you'll be able to let it go more and get some distance.
2017 D&D Invitational
Pretty tight leaderboard with some big names, going out in threesomes due to weather threats. Should make for some good watching.
Simpson has been trending this year of late. He's back on with his putting after several changes since the anchoring ban. I'm rooting for him.
I also like the D&D shops. Ridiculously high dollar, but some good eats.
It's tough to answer without knowing your physical abilities, but my guess is that you will gain some distance since you've only been at it 8 months. In reading your post, you seem to be a student of the game.
What I like is that you are not bothered by this right now - except as a gauge for improvement. In my opinion (I'm not very experienced) and as you stated, trying to keep up with others can be very detrimental.
Be patient, and keep learning and developing your mechanics. Distance will come.
