Learning to take criticism isn't a skill most of us want to learn, but it's essential to getting an objective view of your strengths and weaknesses. This video gives you a start-to-finish primer on how to take, filter, clarify, and apply criticism you receive.
As The Art of Manliness explains, filtering which criticism is worth your time and which isn't is essential to improving. Once you've identified criticism that comes from a quality source, ask clarifying questions and take action where necessary.
Of course, no one likes to be criticised, but hopefully if you're mentally prepared for the times when it's necessary, it's easier to make something productive of it.
