Kendall Jenner is a successful model who gives off an air of cool confidence, but that doesn’t mean she hasn’t endured bullying.

Ahead of National Bully Prevention Month, Jenner is bringing awareness of cyber bullies by sharing tips on how to handle others’ negative opinions.

“Let’s face it – everyone is going to have an opinion. Best advice I have is to realize just that, everyone’s always going to be saying something and if you concern yourself with that, you’re in for a giant headache,” she told Garage Magazine for her cover issue obtained by E! “What matters is how you feel.”

“If you like that picture or you feel good in that outfit, f— it. Gaining perspective does wonders,” she continued.

The 20-year-old admits she follows one simple but profound rule that she learned at a young age: “I aim to treat others as I want to be treated. I know that sounds slightly basic, but when it comes to humans and human nature, the simplest answer is usually the right one. It really is as easy as that.”
