How to find a healthy balance between self-acceptance and self-actualization? Enthusiastic Self-improvement.
One of the most challenging and interesting struggles is to balance between self-acceptance, "I'm satisfied as who I am now", and self-actualization, "I should strive for excellence and actualize my full potential". When facing failure, the former prevents us from negative emotions while the latter motivates us to try more. However, the two mindsets are contradicted each other.
Spencer Greenberg has an interesting approach called Enthusiastic Self-improvement: "I am enough as I am, but I'm really excited about continually becoming a better and better version of myself!"
