The first time I tried to climb a tree was equally terrifying for me as I tried to climb a mountain. There was a fear or FAILURE. I failed in both during my first attempt. The failure with tree was not that bad because it was my backyard & I was just 8 years old. But the first attempt with mountain wounded my calf muscles & knee real bad. I tried/practiced & successfully climbed that same mountain second time after taking a tiny break to heal.
The best part; both incidents/accidents were mad fun for me. Now I have two stories where I succeeded. “SOMETIME FAILURES ARE FUN”.
