Yes, it can be frustrating when someone has it better than you.
But no, they are not the reason you don’t have it good.
They didn’t steal from you. They didn’t trick you.
We all have opportunities. Some much more than others. But no matter who you are, there are plenty of ways to get in the game, and plenty of chances to win.
Resentment isn’t a good way to learn and improve. Curiosity is, though.
Rather than finding reasons to detract, find reasons to appreciate. Keep throwing your hat in the ring, because eventually it will be your turn to win.
