It would be this:
Don't attach your self-worth to your net worth.
So what should you attach it to?
Don't attach your self-worth to anything. Make it unconditional. Value yourself as you are now. There is no time to waste. A meteor could strike the world, and we could all die today.
Love yourself as you are right now. Including the flaws, shortcomings, regrets, mistakes, heartbreaks, losses, and things you did when you were blacked out - all of it. Forgive yourself. Forget the mistakes and remember the lessons.
Love yourself unconditionally. Once you love yourself, you can love others. You love others the way you love yourself. If you beat yourself up all the time, you will do the same to others. Most people are their own worst enemies. You love others as you love yourself, so be good to yourself. Be your best friend and most excellent lover; others will want to be with you because you will treat them well. You will not be lonely, and you will always know that a gangster has your back. Because that gangster is you.
