Not strictly speaking a personal branding item, but I spotted an article in yesterday's Times Career supplement that the WHO now 'recognises' that ADHD (attention deficit and hyperactivity disorder) can continue into adult life. Apparently, the symptoms include a compulsion to move on to the next project once the most challenging bits are done, and getting fidgety after sitting still for too long.
Personally, I prefer to point clients to Belbin's definitions of team roles - not everyone is a completer-finisher; some people thrive on challenge while others are quite happy to let someone else handle the challenges then take over and manage the project through to its conclusion.
Alternatively, take a look at "What Do I Do When I Want to Do Everything?" If you're one of those people who is fascinated by anything and everything; if your bookshelf looks like the main stack at the British Library; if your workshop is full of half-completed projects, fear not: you may be a 'scanner', and the world needs you. Read this book to find out if you are, and why everyone needs a scanner around.
