Over analysing things is a symptom of a mind that is focusing on the wrong things.
It’s a mind that is constantly questioning, second-guessing, trying to figure everything out, flighty, changeable.
It should be strong, centered and focused.
You are over analysing if you are spending too much time ‘figuring it all out’, ‘trying to understand root causes’ and then ‘fixing them’.
It rarely leads anywhere productive.
Just epiphany after epiphany that doesn’t results in any real changes of behaviour.
