Things that make my day: Student thanks

It isn't often that I get these, but when I do, it makes my day:

Hello Mary, I hope you are doing great? I want to use this opportunity to simply say??? Thank you??? for you have been a great influence in my professional career after attending your classes some years back. I am eternally grateful for your influence after taking your courses. I currently work for Ernst & Young LLP, and I do SAP Security & Audit with core specialty in different business processes such as Order to Cash, Purchase to Pay , Inventory management and Financials from a perspective of key risk and controls. Over time, I have become certified in SAP Business Process & Integration, CISA, and Supply Chain etc. I will be honored to give back in anyway to any of your students or help to encourage your students and share industry experience when need be. Let me know anytime i can be of help in any way. Again, Thanks and God bless, Akingbade
