The above quote is one of my favorite quotes. All we can trust is that things will change. Nothing stays constant. My view is that if you are going through 'shit,' you gotta keep moving. Movement helps you know that you are progressing, and one way or another, there will be a light at the end of the tunnel. How do I know? There always is! The situation will change. Circumstances change—life changes. The worst thing that can happen is to get stuck. Nobody wants to get stuck, so, from my experience, always keep moving forward - keep progressing, especially when you find yourself in a shitty situation. One of the reasons (there are many) why I enjoy some of the long and challenging hikes is because of how miserable I get to feel (I know that may sound weird), as they remind me of life. One day you might feel great, and the next day you are exhausted and feel under the weather; you are 4000 meters above sea level, it is harder to breathe, every step is a challenge. All you have to do is keep on moving. You will get to the top one small step at a time. Just keep progressing. We all go through peaks and valleys, whether we hike, compete in sports (as we navigate our athletic careers), grow a business (from my 12+ years of professional career experience observing big corporations but also other companies), and the same is true for LIFE. Stay focused on what you can control, make your world as small as possible, and keep moving.
If your past prepared you to be change-ready, you should be thankful as you will be ahead of others knowing how to deal with change. You will be more flexible and adaptable. Most importantly, enjoy things when the sun is shining, and all is going smoothly, as I am sure you will encounter a detour/ or a roadblock at some point in time. Don't self-sabotage your success and enjoy the ride when all is going well, as things will change. Things might change for the worse, or the better. We never know which direction it might be, but things will change as that's the only guarantee in life, outside of death.
