I know someone who actually makes a POINT of not deciding anything until the very last minute. Drives me completely nuts. If it's a big decision, fine...take time...think it through. But ACTIVELY think about it...don't wait for a bolt from the blue. I'm famous at work for taking decisions out of other people's hands if they faff about too long. Possibly not my most endearing characteristic...but I think it's why I'm the one who's also known for "getting it done." Funny that.
