Highs and Lows

I was interested in this section from the BAB coaching handbook (download here):

From your own experience you will know that everyone has peaks, troughs or plateaus during some part of their training. Recognising this and the ways of dealing with it will be most beneficial to your coaching and to your students. Feelings of inadequacy often come a few weeks after promotion.

I was thinking about this the other day, a bit like walking up a mountain, in that you walk towards a peak, but when you get there you can see there's a higher bit beyond.
