It’s attractive to see someone fired up. It’s not easy to be energetic when you’re very tired. And that phrase ‘I’m just so tired’ is filling the airwaves at present with so many bright young people oppressed by their own work and lifestyle. Build your energy by walking faster, setting yourself tough but achievable timelines, breathing deeper, drinking plenty of water (dehydration is one of the greatest de-energisers) and by staying on the move even when you are in the office.
