I have been climbing the carob tree above a carpark, it's full of "CHOCOLATE" and although I am high up, I only move one (of 4) things at a time; either a hand or a foot. 3 points of contact at all times. What you said about fear of falling reminds me of this parkour classic...
CHOOSE NOT TO FALL.
Sebbyyy! Can imagine you up a chocolate tree ;)
Thanks for the three points of contact trick. Makes sense.
And yeah, I remember this video well. This and Tim's "Imagination is everything".
Luv you buddy!
