“I use this app that keeps my handicap. As professionals, we don't keep...” — Jason Day Quote

I use this app that keeps my handicap. As professionals, we don't keep handicaps. But as a kid, I was so excited about seeing how low I could get my handicap. So that's one app I really do use a lot.

It's emotional highs and lows in the game of golf.

Sometimes I play for the media, sometimes for the fans, sometimes for my sponsors, and sometimes it's for my family. Really, I play for everyone.

Rest is huge because if you're sleep-deprived, that can definitely run into the mental side of the game and can definitely hurt your game if you're playing tournament golf.

If you're going to have a bad attitude, you may as well not even tee it up that week because you probably won't play good anyways.

Google Now supplants the need to open an app by surfacing cards - cards that magically turn into just the information you need, when you need it - without having to go to an app to get it.

For me, my phone is a one-stop shop; I do everything on my phone - email, browsing, listening to music, reading, navigation and using smart apps. Maps, I use that a lot. I think that's the best app ever.

I deleted all the apps. You can actually turn off the App Store. And I gave the passcode to my wife so I didn't have the passcode to reinstall the App Store. And I deleted all social media apps and e-commerce apps.

Prior to the App Store, the chances of that happening, of somebody really young forming a company and in a period of no time really becoming a global provider of a game or something else, it really didn't happen. Now there are these success stories popping up everywhere.
