This school year, as usual, has been a year of contraries. I’m sure I have learned as much as my students have learned, and I’m just as sure I have failed as often as they have. I have flourished and diminished, seen failures and success, shown stubbornness and courage, deserved criticism and praise, endured difficulty and triumph. I have observed and pondered and wondered and worried. It’s been a year of greatness on some days and tedious dullness on others. The sunshine of inspiration has been bright on the best days, and done and gone on the worst days. It’s been a year like a little universe: whole galaxies of fresh ideas side by side with clusters of the silliest mistakes imaginable.
