AJ Jacobs : My journey to thank all the people responsible for my morning coffee

AJ Jacobs at TED Salon  （transcript）
My journey to thank all the people responsible for my morning coffee
Summary
This is a lovely story that the speaker gives us a small idea that we can use from today and it can make us really happy.
It's gratitude.
The speaker is a writer and he realized that a cup of coffee that he drinks in the morning makes him happy and it's come him after many people had worked for. There are people who plant coffee beans, who harvest them, deliver them, and who sell them. Furthermore, people who build roads and shops are also needed.
Why can't we thank them?
Every little thing around us is worth it. Thanking them must be great. Before we focus on the negative, let's appreciate them.
