L50-2: New Year resolutions
I limited myself to two modest ambitions: to do physical exercises every morning and to read more of an evening. An all-night party on New Year's Eve provided me with a good excuse for not carrying out either of these new resolutions on the first day of the year, but on the second, I applied myself assiduously to the task. The daily exercises lasted only 11 minutes and I proposed to do them early in the morning before anyone had got up. The self-discipline required to drag myself out of bed 11 minutes earlier than usual was considerable. Nevertheless, I managed to creep down into the living room for two days before anyone found me out.After jumping about on the carpet and twisting the human frame into uncomfortable positions, I sat down at the breakfast table in an exhausted condition.It was this that betrayed me. The next morning the whole family trooped in to watch the performance.
