In a person's life, no matter what you do, there will always

be people who gossip, there are always be people who tend to judge and criticize you. No matter how sincere you are, some people will give you the cold shoulder and let you down. No matter how kind you are, some people will be dismissive of you.
So, you have to realize that it's impossible to please everyone. What you should do is to find your own path.
Accept yourself, love yourself, and keep moving forward.
