Personally, your e-mail would put you at the bottom of the list. Taffy's e-mail example would elicit a positive response from me.
I don't want a rider to try to tell me what they do or don't know. I will make that decision myself. My first lesson with a new student is very long and it is used as a diagnostic tool to find out where they are and what they know. Most of the time the first lesson is half price and I will not make a decision of whether or not I will take you on as a student until after that lesson.
I don't care if you are not a great rider. All I care about is attitude and a willingness to absorb and learn. My time is too short to waste it on someone who makes excuses and will not try to apply what I teach.
You e-mail makes it sound as though you will be one of those who will be making excuses. Even if you are not, that is the impression given. I have more students than I have time for, sometimes, and I will turn away any who I feel will be no fun to teach.
So, consider using Taffy's example!
