It turns out that two-thirds of Americans don't keep any sort of calendar. Think about how crazy this is. We spend so much time and effort protecting our stuff. We lock up our money in banks, we have home security systems, and we have car alarms. We protect our stuff because we don't want anybody to steal it. But when it comes to our time, we say, 'Come on in and take it; do whatever you want with it.' If you don't plan your day, why are you surprised when someone else plans it for you?
