Is Self Love a Bad Thing?

I've been struggling with my self esteem for quite some time. The key is maybe try to take a break from the self deprecating jokes, because i think that those can get to your head. Don't practise those things when you're on your own. And like looking in the mirror and saying nice things. It's almost like retraining your brain. I mean, it's really, it's replacing the mean and negative things that you say about yourself with nice things. That goes a super long way.
