Which do you think is more of an issue; thinking too much or thinking too little?

There both issues. I know plenty that think to little and spiral downwards out of control.

I myself think too much. An it’s an issue at times as well.

The solution is being able to identify which you are if either and make it work for you. But at the same time also know it can be self destructive an work to improve it.

It’s a balancing act.
