For my opinion, thinking too much
is bad because it leads to negativity. Thinking is a good thing but
over-thinking is bad. This really depends upon how neurotic a person is. Neuroticism is a personality trait and
people who over analyze matters often but not always score high on neuroticism
scales. Thinking too much can lead into a lot of bad things as well like
depression, negative thoughts and lots more. Thinking can be hard work.
Too much of anything is a bad
thing, even with happiness. If you were constantly happy, imagine how bland
everything would seem after a while. You need a mix between the happy and sad
times to truly appreciate those amazing moments. I tend to think that life
works on a rule of balance; every part of nature seeks to find a balance. - Vic
