Sir,
Make sure he sees and UNDERSTANDS the opportunity in front of him. There are many more people out there that I see on the job, WITHOUT opportunity. As a father with special needs children, I know. It's an agony no parent or children should have to endure for a lifetime but so many do. And those are just two facets of opportunity lost......
Make sure he holds himself to a higher standard. As a firefighter, I'm forced to, and that's a good thing....makes it easier to live with oneself. Establish the importance of service, whatever it might be, it will help ground him.
Make him understand competition......AGAINST HIMSELF. If a test gets the better of him, he needs to find out why, and destroy it next time. It is critical to KNOW WHEN THERE ISN'T A NEXT TIME, especially in life, and of getting it right the first time.
ACCOUNTABILITY AND RESPONSIBILITY......'nuff said.
Best of luck to him (and you GO BILLS!
