What was your biggest endurance performance, on which are you proud of?
I used to be very much afraid of heights and I still am, but not as much as before. I tried out rock climbing and it helped me get over the fear. At first I was very afraid of doing it even in a safe environment with the instructor present, but I gradually began to get better at it. It took a lot of endurance to get to where I am now, but there's still work to be done.
