In my working life, it is a great time to have you be the best boss I have never met before, no matter what will happen in the future, I will retrospect for all of what you teach and coach me, will remember all of what you reprove and comment because all of those things can drive me improve and develop myself more and more all the time.
Eventually, I would like to say many thanks for your trust, encouragement, and supports in every things, I will never forget you and you will be my no.1 boss forever.
