Learning from others is vital to self-improvement.

Be coachable. It can be quite challenging to get people to give you advice. So, when you do receive advice, it is important that you are in a position, mentally, to act upon it. If you are the kind of person who ignores advice, then you will soon run out of people willing to advise you.
Learn from feedback. Once you have the advice, take it to heart. It can be difficult enough to receive feedback, so don’t you dare waste it if you are lucky enough to receive it. Some people, unfortunately, rarely get any feedback, living their lives in complete ignorance. Don’t be that guy.
Listen carefully to what others say. Treat their words like precious secret information to be mined for powerful knowledge. With this, you can become a better person.
