Ever feel like you’re pushing a boulder up a hill just to get through the working day? Do you feel utterly drained of energy by the time you clock off and beaten down by the job like you’ve just gone twelve rounds in the ring with Tyson Fury?

Compare this to how it feels when you’re ‘in flow’ – completely absorbed and energised by what you’re doing, and where just time seems to fly in this joyful state of immersion.
