Congratulations on your "Certification". Im sure you will do great. From simply an atheltic point of view, instructor or not, "that" is just amazing. I know its as old as time to say, but I have always believed..
"If you do what you love for a 'living' you will never have to 'work' a day in your life."
To reach that level of achievement, you really have to love what you do.
