Just hanging out around the house in front of mirrors is a great one. I used to be the type who was happy when looking at myself in the mirror and devastated seeing pictures of myself, because I'd alway pose myself at my best angle for the mirror and a pic would never be directly on and would show the actual shape of my person or my posture. I should acknowledge that this method did get me to become healthier so it's not like I finally accepted myself as good but it made me accept who/how I am.
