A Gentleman Does Not Envy. He Is Content With What He Has Or He Strives All The More To Obtain What He Desires.
There’s no need to be envious of what others have that you do not. If anything, it should just make you work that much harder for what you really want.
You see a nice car you want? Work hard to obtain that. You see a beautiful vacation you want to go on? Work towards going within the next year. You see a beautiful woman that has potential to be a girlfriend, well, go talk to her and ask her out! (Before people mention getting rejected, the point is to take a shot. If you don’t even attempt it, then you’re not even working towards it.)
There’s no point in being envious of what others have, because if they have it, you should be able to obtain it as well.
And if you see people being envious of you, strive to be the best person you can be and let others envy that. Hopefully, it’ll make them envious enough to work to be the best person they can be too!
