Lacrosse became a passion for me at the age of 11. The allure of lacrosse has always been the intensity and aggression with which the game is played. 2007 was a spectacular year for the Portsmouth high school varsity team and being part of that team was an experience which I will always remember fondly. After finishing our regular season and playoffs undefeated many of us entered the championship game overconfident. When the final whistle blew we realized our fatal flaw. Much like a tragic hero's hamartia, our confidence, which had helped us to dominate all season long, ultimately led to our demise. Now, knowing the damage cockiness can cause, I am careful not to fall into its snare.

Good evening.

How about, "Now, knowing the damage arrogance can cause, I am careful not to fall into its snare." You could also use "overconfidence," "vanity," or "certainty."

Best of luck!
