For instance, I learned that those who summit Mt. Everest do it in stages. Just getting to Base Camp is a big deal. From there they move on to other camps at gradually higher altitudes. The purpose is acclimate to the thinner oxygen at each camp before climbing higher. They wait for their body to catch up to their ambition.
Work hard, yes, but take some time to acclimate. Don't rush the process and don't de-value the quiet moments. They provide the fuel to carry you to your dreams.
Another thing I learned about Everest climbers is that not everyone who goes to Base Camp defines success in the same way. Many people go along as the support system. Their goal isn't to reach the summit but to make sure the climbers get up and back safely. They succeed only when everyone is back off the mountain and the party begins.
Appreciate your support team in your own climb. Not only will they help you up the mountain, but they'll make sure you get back in one piece! And it's not as much fun celebrating without someone to share the moment.
From Everest I also learned it's all about where you put your focus. I attended a lecture by a young man who had summitted and the picture he showed of crossing an aluminum ladder over a crevasse with spiked boots made me shudder! When I asked how he did it, he said it all depended on where you focused. Looking past your feet was to invite paralyzing fear. See only your feet and you can ignore the gaping maw of ice below you. (Well, he could. I don't know if I could!)
Choose your challenges, define success for yourself and climb on. Let go of your excuses and focus on what you know to be true. Then celebrate.
It's a great recipe for success.
