Show HN: Why Do I Procrastinate? –  Web MD for Procrastination
Procrastination is the avoidance of activity due to a discomfort/fear/anxiety and subsequent inability to scale the discomfort wall that exists between you and the tasks' completion. Other comments mention a pointlessness or lack of purpose, which I consider secondary, since it's arguable if it's truly procrastination if the work is truly pointless. Procrastination as a term seems best applied to important/mandatory tasks. Though, I acknowledge many BS tasks of today's workplace are both pointless and mandatory.
