Wonderful post/reply Blackjack. In a nutshell, I too believe that is what it takes. I'm on my 6th pro-tournament, and I still find myself working on the composure necessary to compete, much less win. My last match was against Tony Watson playing one pocket. I really felt and believed I could beat the guy, but alas, I got cooked. Missed shots that I normally would never have missed. The mental aspect cannot be overemphasized when playing in a public auditorium.
To additional things that I think can help get you there:
1) learn how to sit in the chair (similar to losing with grace)
2) Understand that you will have good and bad days...let the bad ones go.
3) Stay humble. LET YOUR CUE DO THE TALKING, NOT YOUR MOUTH.
A few days after I played Tony, I came out games ahead of John Braumback (sp?)playing 9-ball. I guess that even a blind squirrel can find a nut now and then. : ) Every one has their turn at playing well....keep at it.

Doug
