Commit to Reflect and Reward:
Once the task is completed, stop and observe what has been accomplished.  Take some time to enjoy the “fruits of your labor.”  Allow yourself to feel a sense of triumph and pride.  Next, evaluate what you have learned and decide what you will do differently next time.  Conducting a postmortem will improve your future performance.  Finally, what was the nice thing you had planned to do to reward yourself, your family or your team?  This “reward time” is where you celebrate the great work done by all.  Having a reward planned before you at the start is also useful throughout the process to provide motivation and encouragement when things are not going well.
