"Avoid loud and aggressive persons,
they are vexations to the spirit.
If you compare yourself with others,
you may become vain and bitter;
for always there will be greater and lesser persons than yourself.
Enjoy your achievements as well as your plans. "
(Max Ehrmann, Desiderata)
I've always held the words in Desiderata to heart, especially the stanza above. It has helped me from a lot of stress from envy. There are always people who's going to be better or worse than you, but that isn't what life should be about. You shouldn't envy those who are better, and put down those who are worse. We just need to revel in our time and plans. Good luck with your journey!
