I work my ass off every single day. I deserve to be proud of the things I've accomplished. It is absolutely true that you reap what you sow, & I deserve all the good things that are coming my way. I've earned them all - several times over. I will not feel guilty about the good things in my life.
...and that's what I'm going to start telling myself the next time some ungrateful, undeserving A-hole tries to make me feel any differently.
