I did this today!
When asked to do it, I was at zero confidence level and looked at my instructor in shock. I had a smile that I know asked him how he expected me to do it. He plainly told me to do it and that I can. I started. It was tough. I could not lift my head even an inch off the ground. He helped a little. He motivated a little. And there I was! Such a bloody rush!! Saw the inverted trees and the sun through them. I was beaming after that. Still am.
Yes, small things can be a big deal. For me, always are!
