This is a very valuable lesson because these people are going to be the ones who shape your life and help you fulfil your dreams.
Stop trying to be the person you think others want, be you. Then find people who appreciate you for who you are and encourage you to go out there and be the best that you can be.
They may be a little harder to find but when you do it will be totally worth it.
Make sure you surround yourself with friends who know your true worth!
