One of the things I often tell people is that there are really only 6 emotions;
Joy
Love
Surprise
Fear
Sadness
Anger
Everything else we feel is usually some derivative or variation of these 6.
Attached is a chart that I have been using that I really like, which comes from the Junto Institute for Entrepreneurial Leadership. I have no affiliation with the Junto Institute, I just really like the graphic they have put together.
