Life gives us great feedback.
If you were to stop and take notice of what is going on in your life; you may find some really helpful information.
What people are saying about you, can be great feedback?
If one or two people are saying something negative about you; then, OK, fine; but if many people are saying the same negative things about you. It maybe time to take a look at yourself.
It can be really difficult to accept and explore these negative things within you. It takes courage and honesty to see where you need to work on yourself. You may just discover areas of your life that could benefit from a little attention and once you take responsibility for this; great change can happen.
