I like psychology, but sometimes psychologists say some weird things. Here are some examples from recent newspaper articles.
One said that how you handle your e-mail inbox says a lot about your mental health. If your inbox is tidy, your mental health is good. If it is full of junk, your mental processes are not working well.
Another article suggested that your tennis game reveals whether you are angry, sad, narcissistic or neutral.
These maybe true, but I grow weary of psychologists who want us to turn everything we say and do into a revelation of our inner life. Introspection is good, but it is not the only thing in life.
So I set you free to handle your e-mail inbox however you choose, and when you play tennis, just have fun.
