Procrastination is the bane of so many people's lives but it's not an indication you are lazy, or stupid. It's not 'just your way of doing things' nor is it a really great strategy (although deliberately putting a gab between starting and finishing is brilliant for maximising creativity and producing inspirations).
It is an indicator something more is going on; and once you work out what the something more is, suddenly the procrastination can disappear!
