How to Live Your Passion and Wildly Succeed

"Anything insane has a price. If you're serious about building your personal brand, there will be no time for Wii. There will be no time for Scrabble or book club or hockey. There will be time for meals, and catching up with your significant other, and playing with the kids,  and otherwise you will be in front of the computer until 3:00AM every night. If you're unemployed or retired and have all day to work, maybe you knock off at midnight instead. Expect this to be all consuming."
