They have a passion for what they are doing.  They are excited about what is happening in the industry.  And when it comes down to it, for all of us, who may be jaded by the business or tired of the "sameness" that we see each day, it takes an infusion of passion and joy like these men exude to really get us involved.  It is going to be people like these men who lead us and want us to experience wine like they do.  I feel rejuvenated.   That's the secret to success.
