When people talk about Abundance Mentality they are usually talking about it in regards to women. It's not wrong, my relationships go so much better when I have abundance but your whole life goes easier when other categories have abundance too.

Ever catch yourself getting butthurt your buddy didn't text you back or won't reply so you can play golf. If you have multiple friends you don't get bent out of shape when one or two don't hit you back.

Have multiple job offers? Now you can twist them into what you want and make them compete for YOU since you are the prize.

I'm not even going to mention the benefits of women because everyone here should already know but apply abundance to multiple levels of your life and feel yourself become happier. Just my 2 cents.
