I tend not to do it when my supervisor is with me in the room, but if I am alone (as I tend to be lately), it flares up immediately. There are deadlines to meet and things to do, but I feel that once I've got my head "up in the clouds" I don't seem to be able to get back down and keep busy with the drudge of the job.
Do you have any suggestions or tips specific to the workplace? Or things you want to share?
