Be careful what you wish for.
You have lots of good suggestions already.
I kept the depth of my passion for pool from my son for over two decades. He had great eye-hand coordination as a young child playing sports and I greatly feared that he would see the "easy money" available in pool. It comes at a great price and I wanted more for him.
I made sure that he received a college education. He went on to further his education and became successful in the computer field.
Now, once a week, he and dad go out to play in a weekly pool tournament, only practicing one hour before the tournament. I get a chance to pass on some of my "secrets" during that hour and he has proven me correct about his ability to learn how to play pool. We have fun. I try not to push off too much on him because while he is competitive, primarily it is just a chance to hang out with his dad for a little while. I feel a lot better that we are sharing my love for pool at this stage of his life, rather than earlier.
In his earlier years I supported him with football, basketball, baseball where he was an All Star, wrestling (where he won the State Championship in his weight class in 8th grade lol) I would pay a king's ransom for videos of those wrestling matches but the memory alone brings a lasting smile to my face every time I think of them) Hobbies of metal detecting took us places where we discovered the treasures of yesteryear. Hunting and fishing filled in the voids for us and I have to say I don't miss the fact that we didn't share pool in his younger years. In fact, I feel like I was most fortunate in that regard.
Even now as a young single guy with money to burn from the earnings of a well-paying job, he now realizes the repercussions from doing any serious gambling with both winning and losing. He sees that people who can ill afford to lose money suffer when they lose. The little money that he could earn gambling won't make a difference in the quality of his life. The feeling of losing large sums of money aren't pleasant for anyone and it's not likely that he will ever go down that road either. So in many ways, not sharing my love of pool when he was at an early age, turned out pretty good.
Merry Christmas!
