This is a very interesting vlog. I think that when getting older we tend to loose this capacity of doing stuff that seems difficult or challenging. We underestimate our capacities and prefer to stay within our comfort zone. What you are doing with your comments is actually giving people a real feed-back and an encouragement to continue on their path. Self-confidence is the first step to gain and this will help to get out of the confort zone and to achieve something new. This is the key to evolve and to innovate.
