I heard somewhere that to grow in life one has to be dissatisfied. If I’m satisfied, I may not want to grow in life. What should one choose to grow further in life — discontentment or peace of mind?

Will dissatisfaction give you peace of mind? It can give you the road map for growth but will it give you happiness? No. Acharya Mahapragya said, be dissatisfied with the knowledge  you have gained and be dissatisfied with your actions or the things that you are not doing right today. Material wealth and prosperity alone can never give you complete satisfaction.
