What have I done today to be helpful?

A few weeks ago I had a man come in for a One-on-One. His requests were fairly straight forward and he was quick to understand the mistakes he was making. It was really nice to be able to help someone who was so eager to learn. Just the other day he came in for another One-on-One and he decided he would show up a half an hour early. He said, "I know this is your last week and I want to use your brain as much as I can." Seeing how he was so nice, I gave him a two hour session and at the end he couldn't stop saying how much I had helped and that I should stick around for the year. :)
