Dear Professor Bassell,
I am writing to thank you for all you have taught me in business. The knowledge and wisdom you have imparted upon me has been a huge help and support throughout my college studies and hopefully career. I believe my accomplishments and success is at least partly due to your sincere support, positive encouragement, mentorship, and coaching abilities. I want to express my deepest gratitude for believing in me and constantly reminding me that I have the ability to do anything. You have been an excellent coach, professor, friend, mentor, and a great inspiration for me. You have inspired me to pursue my goals with hard work and dedication. You have shown me the value of sincerity, honesty, and trust in business. I truly value and appreciate everything you have taught me and done for me. It will forever remain a major contributor behind my success and achievements. I hope one day I can do the same for someone else. Thank you, once again, for your time, patience, and positive support.
