If it’s important to you, do it early. That means if exercise is important to you, it’s best to do it first thing in the morning. If you’re writing a novel, it’s best to have written most of your weekly pages by Tuesday of each week.

The reason is: the later it gets, the more likely you are to be distracted and avoid your task. The best time to get something done is in the morning when everyone else is still half asleep.
