If you have a mammoth task ahead of you, begin with preparation, proactivity and research.
Next break the mammoth task into many bite size actionable items. As you complete the small actionable items, you gradually begin to see the light at the end of the tunnel. As you progress through these steps, the task is no longer as daunting.
The most gratifying thing is that you actually end up performing remarkably well in the end. So what starts as a mammoth task, ends up being an enjoyable and fulfilling experience!
