If you don't love yourself, you'll always be chasing after people who don't love you either.
Be thankful for all things in life. Even for the bad things. Sometimes the worst situations in life turn out to be the best things that ever happened to us.
Go on and be great. Give them something to talk about.
There will be haters, there will be doubters, there will be non-believers, and then there will be you, proving them wrong.
