Have you ever had a competitor in something? If you're saying no, and you're a human being, then I'm not exactly sure if I have any good news for you, or maybe you just don't know. The truth is ever since we've existed, even before our birth we've competed.
You've competed with the other spermatozoa to get to that fertile egg.
You've competed with your siblings for food, toys and attention.
You've competed with life issues for survival each day.
You even compete with gravity - every day that you stand up again.
