Make decisions for yourself
Not knowing how to think for yourself—essentially, being a puppet—is an incredibly dangerous position to be in. It means that your life is in the hands of the most convincing argument, not your own analysis of that argument. This doesn’t mean you should be arrogant or ignorant, but to never make a decision without considering information against your own point of view and values. Blindly following others is a guaranteed way to live a miserable, mediocre life.
