Twas for me, numerous little things, forget take off flap, out of trim, twice left pitot cover on & didn't notice till I was over the barley at 200ft. Very hot day, full tanks uphill take off no wind, trees very close!! Got a bit of instrument instruction once. Base leg turn he asked "Do you normally approach at this height?" Closed the throttle on me & asked "Are we going to make it?" "No, were in the barley". I learned a lot fairly quickly. I think the training kicks in with important stuff.
