Back in 2005, my coach, David Whelan, gave me a challenge that seemed simple enough: to chip six balls from just off the green and get each up and down. It was the morning after my first missed cut on the LPGA Tour, and David was insistent that I spend my practice session on chipping and pitching. I told him I'd get all six balls up and down in three attempts or less; instead, I needed 57 attempts, and it took almost three hours.
