@Part_of_Shiva well that's the whole point of being alive- losing, eventually. That's the one constant- we like to call it change, but really it's loss and us rising again form it. You're human- you're allowed to feel jealous. But that doesn't mean you should act on it.
And giving up just because they beat you is doing exactly that. Why should you think you should always win? Why should you think you're invincible? They won. And you didn't. Life happens.
And the once you defeated aren't standing supreme. The ones standing supreme are ones you had been able to defeat at a certain point of life. Then they got better. maybe their worked on themselves. Maybe luck finally smiled upon them for a change. Eitherway that's how life works- new empires rise, old ones crumble. And as long as you're alive, you fight again.
