Dogma is a principle or set of principles laid down by an authority as incontrovertibly true. Dogmatism get individuals into unwarranted hardship because they ignore evidence that does not support their line of thinking.
Rigidity in one’s thinking comes with dire consequences. It does not encourage people to develop an open mind that will encourage them to check in with themselves from time to time.
It is better to have a flexible mind than to uphold dogmatic beliefs. You stand to benefit a lot from keeping an open mind.
Open-minded people are more optimistic and they tend to enjoy more of life’s goodness.
