It is almost the end of 2023, looking at what is happening to the world today, the wars in Ukraine and Israel, political polarization in America, and wealth gap between the rich and the poor, etc., it doesn't give us more reasons to believe that those bad things could make 2024 better. Plus, all those things could bring additional bad feelings to us, especially among the younger generations. Meanwhile, Professor Krista Thomason, author of a new book called "Dancing with the Devil: Why Bad Feelings Make Life Good," explains why we should be hopeful and positive, as we step into 2024. All those negativity and terrible feelings could be seen as tangible mechanisms for positivity.
