Comparing yourself to others is nothing but bad news. Why? Because we're all on different development timetables. Socially, mentally, and physically. Although some of us are like the popular tree, which grows like a weed the moment it's planted, others are like the bamboo tree, which shows no growth for four years but then grows ninety feet in year five.
Life is like a great obstacle course. Each person has their own course, separated from every other course by tall walls. Your course comes complete with customized obstacles designed specifically for your personal growth. So what good does it do to climb the wall to see how well your neighbour is doing or to check out his obstacles in comparison to your own?
Building your life based on how you stack up compared to others is never good footing. If I get my security from the fact that my GPA is higher than yours or my friends are more popular than yours, then what happens when someone comes along with a higher GPA or more popular friends? Comparing ourselves makes us feel like a wave of the sea tossed to and fro by the wind. We go up and down, feeling inferior one moment and superior the next, confident one moment and intimidated the next. The only good comparison is comparing yourself against your own potential.
