I think it can also be the other way around - self love leads to willingness to introspect and to be self-aware - because you love yourself, so of course you care enough to pay attention. If you think you’re worthless or broken, why bother waste time digging into yourself to find out who you are and why you do the things you do, what you really want? What benefit could there be - as a matter of fact, couldn’t there only be the risk of pain?
