Sadhguru
How do I stop feeling jealous when others do better than me?
Strive to be your best, not better than others
Finding pleasure in being better than somebody, or enjoying other people's failures, is a sickness. Every life in creation is striving to its best, and so are you, so there is no reason to be concerned about whether somebody is behind you.
Every life in creation, from a worm, insect, bird or animal to even a plantain tree, is striving to be its best. You too. So why are you concerned whether somebody is behind you?
