When my youngest brother was in high school, he set a significant goal for himself—he was going to dunk a basketball. But there were some up-front problems with this goal. For starters, he was the shortest kid in our family, topping off at 5'8". Plus he had never played scholastic team sports. But Greg was determined.
We had an adjustable-height basketball goal, and Greg would go out and practice. But it wasn't until years later in the college gymnasium that he finally dunked one. To my knowledge there were no witnesses, and I'm not sure if the feat was ever repeated. In fact, I never heard another word about basketball from him after that. But he did achieve his goal.
Speaking of goals, what goals have you set? Are they SMART?
