None of us chose to be born in our bodies or as humans (as opposed to aliens or AIs or whatever). Our brains have to make the most of the circumstances given to us, and we spend our entire lives trying to do this.

Jealousy, the desire to spite others, spread rumors, speak negative or ill, feel self-pity - these are further evolutionary games we play to climb the fitness landscape and escape local minima.

The rewards of this life are finite and your biology will always want more. Even if you're the richest and most handsome person, the hedonic treadmill will keep you running. However high the highs are, they're finite and ephemeral. Everyone living on this earth with you today will be dead in ~80ish years. And that's the blink of an eye. None of their riches or victories or accolades will go with them anywhere.

Look up, not down. Build towards a better tomorrow. Don't worry about other people. Be the best you can be.
