People with ADHD each experience its effects diversely, says Henry Shelford, chairperson and co-founder of charity ADHD UK, and there’s no way to know how it’ll appear in someone’s life. Some struggle with being on time, or keep a desk that looks like something exploded, for instance; others are neat as a pin and always punctual, yet can’t stop themselves from interrupting in conversation. Some people, says Winter, only tend to do what they’re interested in – “what lights up our brains” – which causes them to de-prioritise other urgent tasks.
