The biggest thing that you can do for you is to educate yourself on what is great about you-then focus on being the best version of you that you can be.
It sounds SO SIMPLE-but it really requires effort to make yourself do it. (ugh).
Also-if you focus your mind on helping yourself and anyone around you be the best that you/they can be, you have a lot less time to contemplate who is better than who-because we are all REALLY only competing against our own best self-not everyone else.
The first step is to commit to making every decision EVERY decision based on "is this promoting my best self-or not". If it is-go for it. If it's not-don't do it. No matter what it is.
