how do you make yourself less jealous?

I think I am missing the jealousy gene altogether. 🤷‍♀️

Teach yourself to be happy for others. Work on your insecurities and try to remember that we all have our own things unique to us, thus shouldn't feel jealous.

A decent dose of reality... There are always going to be people who are better ( whatever) than you... Get over it, just as you are going to be better than others.
Stop comparing yourself to others and just be you!

I'm not jealous much or often but I negotiate to have my needs met. If your needs are unmet, it's much harder to share your relationship resources.

I overcame jealousy by finally realizing that it was based upon my own insecurities, so I worked on that.

Just try to love yourself and don't focus on others

For me it was time and maturity.

You need discipline 😁
