The Quest for Personal Mastery took me on a journey of self-awareness and discovery for which I will forever be changed. Understanding my mental models and addressing limiting beliefs was so huge. I've learned to LISTEN for understanding. Just this act alone has deepened my connections. I also realize that many of my limitations are restrictions that I've placed on myself. They're not really real.
Another ah-ha moment was the lesson about "Good thing, bad thing, who knows?" I don't think a day goes by when I don't think upon this concept. Just saying good thing, bad thing, who knows has reduced my stress level when handling challenging issues.
