For me, this is really a thank you letter.
"Joe, thank you for sharing in my work. For helping me build the structure I've needed to take my work to a higher level. Thank you for helping me discover the very core of my passion and how that can impact the world around me. When I start over thinking or when doubts rise, you’re a strong voice of reason and practical help I need to keep pushing through the blocks that used to hold me back.
What makes you stand out is you’re not only a very experienced and capable coach, you’re an extremely inspiring, creative, and trustworthy person. I can trace all the brave choices I’ve made and all the new connections and successes I’ve experienced, directly to a principle you shared, an exercise you had me do, or a word of encouragement you shared with me. Forever grateful for you!"
