Imagine you have six months to live.
What would you do?
Would you finally take those guitar lessons?
Perhaps you would invite your parents over for dinner and tell them you're happy with how they raised you or whisper into you're partner's ear you want sex. Now.
But why wait until you're about to die? What's stopping you from doing the things you want to do today? Work? Sure. You put eight hours a day into your job. Maybe ten, including travel time. Eight hours for sleep and two for household chores and eating. Leaves four hours every single day to do whatever you want. But most people prefer to watch TV and surf the internet.
How come you do have the time to watch season 2 of Friends. Again. But don't have the time to take advice from your mom or anyone else?
Of course you could go on watching TV and surfing the Internet for four hours a day. But what keeps you from helping your elderly neighbour? Or following your dreams. Perhaps you want to keep on working until you have enough money. But when is it 'enough'?
