One of the most interesting things I got out of it is that your memory of an event can be completely different depending on the very last part of that event. In the talk he uses colonoscopies as an example, but it can apply to anything.
Yesterday I had an ok day at work. It wasn't really significantly better or worse than any other day this week. However, the very last thing I did before finishing up for the day was call a new client, and it put me in the BEST mood. He was super enthusiastic and excited to get going, and it made me excited and motivated to make things happen too.
I left work feeling energetic and looking forward to the next work week. And unlike most weekdays, I not only felt up to cooking dinner, but actually wanted to make something awesome.
I first thing I said to my mom that night was, "I had a great day a work!" and looking back over everything that had happened, I realized it was all because it had ended with that phone call.
The free taco bar for lunch was pretty cool too ;)
