This message is a technique by an individual I really admire from Joel Brown. In his coaching business, he gets results by encouraging his clients to step outside of their comfort zone.
I recently implemented this for myself and put it up on my wall, and although it’s too early to advocate completely for it I want to share the theory behind it. First, it is very visual and a constant reminder of what you want to achieve, serving a similar function as a vision board. Then, when you do achieve a stretch goal, you get the validation and reward of expanding your circle, which motivates you tackle the next one. And last, it forces you to specifically list things that exist outside of your comfort zone, and in the pursuit of achieving them you experience growth as you navigate new frontiers, making the uncomfortable more comfortable.
