Today's Gratitude Item: Being appreciated :) My principal paid me a visit today and told me that they would be paying me a bit extra because of some of the work I've been doing. Said work has to do with e-learning and I thought it was part of my job (seeing as I now teach IT). Needless to say, this news was a fantastic surprise. The extra money is great - but being noticed / appreciated and acknowledged is what really matters.
