Be honest with yourself and know your delusions
Everyone is delusional about something in some way. How we look at certain groups of people, how we look at ourselves, or our general outlook on life/the world. At the very least, it’s important to acknowledge when we may be delusional about something and try to see how we might move away from that. It can be hurtful and painful to do so, but if your goal is to move beyond what’s holding you back, you need to be honest with yourself and start making the steps to move in a more positive direction.
