In the mountains, as in life, things aren't always easy. There are many failures and lessons along the way. Each of which, if you choose to learn from them, will help you grow. The hardest times will often lead to the greatest moments. They make you that much more resilient. Remember to trust the process and do the work. Great things don't magically happen overnight. Make incremental changes.
Some days it feels like one step forward, two steps back. Other days, it feels like you're sprinting uphill. Even in the darkest times, all that matters is that you keep pushing on. Stay focused on your goals and be true to yourself. Cut out all of the noise. Eventually, you'll reach the summit, one step at a time.
