Steal a March
Life can have some chunky, discrete outcomes. Catching the train. Starting a relationship. Promotion. These outcomes often depend on arriving on time or even early. A sense of urgency helps. If U run or jog U might catch a train U otherwise wouldn't have. That can make the difference between showing up early or late to an interview.
If U plan ahead U won't need to rush as often. U won't regret speed if U make no mistakes. Sloth U'd consider a mistake almost definitionally though.
