There is also the first 45 seconds of this video. He specifically states 4 times a year is the goal and he uses the other tournaments to prepare for the majors.
Seems none of those quotes said he does not care at all about the other tournaments and its only about the majors.
Yes...his focus is the majors...his main goal...but bolded where he talks about the others with the majors and not as if they are just nothing.
What you bolded was followed with an "
and win more major wins that anyone else in the same year, then it's been a good year." So by Tiger's own definition he's had not good years for 2009, 2010, 2011, 2012, and possibly 2013.
Also did you watch the video?
I try and peak 4 times a year. I try and peak for those for majors, and uh every event I enter is to win. So, you know I use the other tournaments as....um...yeah you try and win 'em and I have won tournaments in the past, but in the end I'm trying to get mind, body, and spirit all to come together for 4 weeks a year. If I get in for those 16 days, I think I'm going to have a pretty good career.
Interviewer: So 18 majors what would that mean to you?
TW: "I think that's the Holy Grail of our sport."
