We may be getting a bit off topic but I think a connective strand has been established. Some things take a bit of thought. Being prepared is always a good thing.
I was not originally what most would call a slow player but I was not a fast player. I think the reason is because I controlled 'me', the cue ball, very well. Most faster players, IMO, shoot the shot, perhaps with an intention to control the cue ball but not really too concerned if it does not go exactly as they intend.
Then I had a small eye accident & I became a slower player, not too slow, but what many might call a slow player, as in not a fast player. The reason was that due to my astigmatism from that small eye accident my not perfect vision put some doubt in my mind.
Now keep in mind, I'm talking about cheating pockets & using english very very much of the time.
Recently I found out that, for pool, I am cross dominant, & for pool, should be using my left eye. So recently, I have been playing pool a completely different way than I ever have.
I'm now playing so much faster that many might say that I am now a fast player.
The reason is that I have almost no doubt in my mind as to whether I am seeing correctly.
I guess what I am trying to say is, that one can consciously speed up or slow themselves down for whatever reason, but... I tend to agree with Ms. Crimi that the true issues are more deep rooted & are generally related to a psychological nature.
In golf, tempo can be very important & going against one's innate tempo might be a fix of some 'timing flaw' temporarily. But... in the long haul going against one's 'nature' rarely if ever works out.
If you're a thinker, think, but do so efficiently.
If you're a carefree type, give it a bit of thought.
Usually, Balance is best.

PS I would be considered a slow golfer too, but... I never made anyone wait on me.
PPS I would suggest that most should listen to Ms. Crimi. She generally has a wealth of knowledge as well as IMO incite way beyond most instructors or any that give out advice & that certainly includes myself.
