Let's say that my original aim was to make $100,000, which I then changed to $1 million. Which of these goals would you rather come up short on? Some people claim that expectations are the reason for unhappiness. However, I can assure you from personal experience that you'll suffer greatly by setting subpar targets. You simply will not invest the energy, effort, and resources necessary to accommodate unexpected variables and conditions that are certain to occur sometime during the course of the project or event.
