I think everyone should want to compete against the best in their sport whatever it is. The good thing about sailing is that even when you are old/older you can still compete with the best if you have the knowledge. Plus, racing against the best let's you know how you are progressing.
And believe me, I know all about how hard it can be since I moved to Pensacola with 3 years sailing experience on Hobie 16's and about 6 races total under my belt.
