'The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.' Alvin Toffler
In today's world, unlearning is an essential skill. As old concepts become obsolete in no time, you constantly need to let go to make room for creative processes resulting in a new understanding.
How can you unlearn? Let go of your pre-set worldview by meeting other people and by understanding how differently they see the world. Another approach is to travel to places that disrupt your thinking or to engage in regular experiments in your life which take you out of your comfort zone.
