Help me to write a short paragraph to my previous sir thanking him that if it wasn’t him I wouldn’t have new some of the accounting basics

Dear Sir, I just wanted to take a moment to thank you for all that you have done for me in teaching me the basics of accounting. If it wasn't for your guidance and patience, I wouldn't have the foundation of knowledge that I have now. Your dedication to my development has not gone unnoticed, and I am truly grateful for everything you have done for me. Thank you for believing in me and helping me along my journey.
