This this the mental attributes to succeed in golf (profesionally)?

All, you have to do, is keep bad thoughts out of ya head, think ya the best on everyshot, keep telling yourself, your a good putter, chipper, iron player, driver of the ball. Keep concentration on what your doing!! Keep eating food, little bites, Sandwhich's, twiglets, chocolate but just a thin layer of chocolate. And if you feel thirsty its 2 l8, ure already dehidrated!! Self talk, i.e. if you hit a few bad shots in a row, talk 2 ya self and take deep breath's if you feel pressured, before shots!! All this has helped me!!
