It took awhile to believe in myself. When I started working with my psychologist, Alan Fine, in 2004, there was a noticeable difference in my game. We had a life-threatening issue with my wife in 2005. (She is a nonsmoker but was diagnosed with lung cancer; she's doing better now.)
After that, every year has been a great year. Fine tried to get me to play more naturally, like Stephen Ames the instinctive player rather than Stephen Ames the technical player. It's still a struggle.
