We love positive criticism, but not so much the negative. Why? There are many reason that humans don't like the negative. However, the negative, if constructive, is just as beneficial as the positive. For true change, and going off after your goals, you need to find honest, trustworthy people, who are willing to give you positive, and especially negative constructive criticism. It will provide impactful benefits for your change and your life. Let go of your ego and let your guard down.
