Set up the shot, ok
Shoot it 500 times, No chance!
The same exact shot over and over for hours?
I know there are folks on both sides of my opinion , both deeply entrenched on either side so let's forego that debate lol. My opinion is that after getting basic Instruction and reaching at least a minimal speed the best way to become a " player " putting yourself out there, putting up YOUR OWN CHEEZ, and gettin in action ! !!!
As half Jack mentioned, there is absolutely ZERO chance that I will get a table of my own for hours on end and shoot the same shot 500 times or however many times lol! However what I would / could / should do is get in action and that shot you're supposed to shoot 500 times WILL in fact come up over and over again while I'm in action , AND when it comes up you can be DAMN sure that the shot will command my FULL attention, and my absolute best effort to make said shot. Now can I say the same things about the shot if I'm alone on a table " practicing "??? He'll no lolol. I would have been " practicing " " that shot " for probably every bit of 2 minutes before wanting to kill myself from boredom. The end result would be me slamming a 5 rail bank a 1000 MPH just to see if I could get it to drop ONCE -
Again I'm being completely serious but definitely a big LOL! Just as in life, different things work for different people and if lessons and practice truly gets you to where ya wanna be then so be it, wish ya the best of luck but for whatever the reason it just isn't my cup of tea.
