Not-thinking can also cause depression, whereby you don't think about your life, what causal factors have led to your current condition. When you know more about yourself, know thyself, you can be empowered to do something about it.

Thinking is a problem when you over-think and obsess over something but don't actually think deeply about it to understand the situation. You just keep thinking about the effects of the problem, but not the root to find the answer.

Thinking needs to be developed.

Take care. Peace.
