The nine types of stalling that researchers say can reveal something deeper about us and why it's not always bad.

I'll just do that later, this thing can wait, maybe a short break first... We've all been there: putting off certain tasks then being left with essays up to the wire, loads of messages unread and that bedroom sort-out that just never happens. A fifth of us are guilty of regularly procrastinating but the type of procastinator we are can reveal something deeper about us, say researchers. Are you a dreamer or rebel? Hedonist or a thrill-seeker? What does it all mean, and can you fix it? The cause can be hidden or buried, says Dr Itamar Shatz, a lecturer at Cambridge University who is publishing a book on the subject this week. According to Shatz, people can be any of nine types, external, sometimes simultaneously. Dreamers, for example, fantasise about the future too much, while rebels feel a lack of control and so procrastinate in protest. Hedonists care too much about immediate pleasure, thrill-seekers enjoy a deadline at their own peril and zigzaggers switch too often between tasks. The other types also embody their names - worriers, pessimists, perfectionists and burnouts who are tired from working too hard.
