Do one thing at a time. Do NOT multitask. This is very difficult. Even if you minimise distractions from devices, tech etc, there are still your dear colleagues who may approach you. And even if you can isolate yourself from them, there are still the swirling thoughts in your mind! You’re writing a report, but your brain keeps reminding you of that task your boss gave you before lunch and that just triggered a series of thoughts about your last review…aaaggghhh!!! It happens to all of us, so don’t beat yourself up too much when you get distracted. Just always be clear about what single task you are supposed to be doing (e.g. have it written somewhere) so you can get back to it as quickly as possible post-distraction.
