Manuel Loigeret writes about going through imaginary walls and why we need to stop putting people on a pedestal. He uses many examples from his own life -- learning computer programming, learning English, moving to Canada -- to demonstrate why we need to go through the walls we perceive:
There was some fear, that’s for sure, but I don’t think this is the core of the problem. The real constraint was other people. Those who made it and told me it was extremely difficult and nearly impossible. The coders who made me believe that their code was cryptic. Those who told me I could never stand the cold winters of Canada. The teachers who told me I would never be good at speaking/writing in English. Those who told me yoga was only for girls. Those who told me you can only evolve in your career by working from 9 to 5, etc... All these people building imaginary walls to cover their (lack of) knowledge so they could stay in their fortified ivory towers.
