I'll be the first to admit it is not necessarily enjoyable to receive criticism of ideas or products/services that you have put time and effort into. Criticism is part of life and in all actuality, should be embraced. How so? According to Ray Dalio (worth billions of dollars), you should view any type of criticism as an opportunity. Through my own personal experience in life, I can attest to the fact that what he says is definitely true. Again, criticism may not be enjoyable, but it is worth it when you have the right attitude.
