There are sweet rewards for reaching your goal. Better health, more time and money to spend doing the things you like. There is even more than the reward at the end of the road, there is the road itself. As others have said, it’s not only the destination, but the journey. The journey, as it turns out, is something you can measure.
For example, if you have set a target weight for yourself of 110 pounds, and you presently weigh 150 pounds, then the “journey” is to lose forty pounds. All of this is measurable: your present weight, your target weight, and the pounds to lose on the journey there. Measures can be recorded, compared, analyzed, and otherwise used to determine how well (or how poorly) you are moving toward your goal. Measures can make reaching your goals easier and help motivate achieving them by breaking the journey down into smaller segments or sub-goals.
An analogy from American football illustrates this. Each time the offense steps on the field, their main goal is to score a touchdown. But unless they go for the “hail Mary” to get the touchdown in one long pass play, the team will try to get a series of first-downs. Each first-down is a segment or sub-goal that moves them at least another ten yards toward their goal of a touchdown.
Similarly, if you want to lose forty pounds, you will not do so overnight. Nor likely in a month (nor would it be healthy to do so). But (with your doctor’s approval) you might be able to lose eight to ten pounds in a month. Or a smaller segment might be a pound or two in a week. The point is, a measurable goal is easier to achieve because it can be broken into segments, one step at a time.
Measures also serve as milestone markers. You know where the halfway point is. Set it as a milestone. When you achieve the milestone, reward yourself. Good job! Go out to dinner and take in a movie, or enjoy a special weekend. Maybe buy a new hat or purse or electronic gadget. Milestones can be anywhere along the journey. Divide the course into quarters or thirds or whatever, and when you successfully reach each milestone, celebrate!
