You can’t be at your best all the time: performance is expensive to maintain, day in, day out.
Learn to recognise when you need recharging, and take a day off. Don’t wait until you’ve reached the end of your tether – that’s when it’s too late.
A day off in the middle of the week when everyone else is working or a long weekend can do wonders for your energy and morale.
You’ve earned those days, give yourself permission to use them when you need them.
