End on a good note!

Regarded as one of the most influential living psychologists, Daniel Kahneman won the Nobel Prize for his pioneering work in behavioral economics. His lecture "The riddle of experience vs. memory", teaches us two important lessons:

1. Our perceptions . . .well, don't trust them all the time. 
2. The final parts of an experience are disproportionately  heavily weighted in our minds. They leave a more lasting influence. So if you are crafting an experience, end on a strong note.
