How to deal with jealousy

Sometimes my mind drifts to seeing bad people get good things in life and having no bad consequences of terrible behaviour.

I see them having easier lives - even if people around them suffer - atleast they seem to get what they want.
I'm a pretty independent person who prefers not to rely on anyone and be as self suffient I can be and try not to bother others even if things are diffcult to me.

But seeing some people live their life totally the opposite way - frequently makes me wonder if I am being studpid being virtous and self sufficient.

How to deal when these feelings of jealousy come up.
Happy to hear if there is a mindset issue I have.
