2 . Letting jealousy win
One of the natural traits of human is jealousy, but this feeling must not take over your life or else you will end up living a life full of regrets. Try controlling it and accept the fact that each person on earth is blessed with different things. But if you still want to have as much as someone else then work hard and fulfill your own wishes. On top of that, start by being grateful for what you already have.
