There are 6000 emotions that we have words for in the English language, which is just a linguistic representation and changes according to language. What’s interesting is that if monitor ourselves for a week and record how many emotions we experience around that time, we would only have 12 dominant emotions during that time.
We all know someone who no matter what happens finds a way to be depressed similarly we all have one friend who finds a way to be happy no matter how miserable his life may be. So basically there are two categories of emotions, empowering and disempowering.
We are indirectly controlled by our own emotions, observing what drives us and using it for our own good can make a world of difference to us.
