Success can bring a sense of accomplishment and fulfillment, but it should not be taken as the end of the journey. Similarly, failure can be discouraging, but it is not the end of the road. What matters most is the courage to keep moving forward, to learn from mistakes, and to continue pursuing one's goals.
Ultimately, the phrase suggests that success and failure are both part of the journey of life, and what matters most is the ability to keep going, to learn and grow, and to never give up on oneself or one's dreams!
