Consider how to focus on your recovery. If you try to nurture your body back into health after physical stress, how can you apply that principle to mental stress?
Activities that leave you mentally refreshed – things that require mental stimulation not just physical stimulation.
Be selfish – protect yourself.
Don’t live the emotions of other people.
Turn the emotional temperature down.
Try to predict, and prepare for, times where the challenge is higher than usual.
There are two things at work here: the degree of challenge, and the degree to which you can cope. Can you focus on each thing individually?
