Allow time for recovery
Our muscles need time to recover form exertion before we exert ourselves further if we are not to strain them. The same applies to our mental and emotional ‘muscles’. If we keep stretching ourselves in our work efforts (and in our lives more broadly) without giving ourselves time to recover, we run the risk of doing ourselves harm, potentially significant harm. Exertion plus recovery plus more exertion can produce growth and development (of muscles in the direct physical sense or of learning in our more metaphorical sense). Exertion followed by more exertion without recovery time in between can produce muscle strain and/or psychological stress. Time for recovery is therefore not an optional extra of we are to take our physical and mental health seriously.
