"Look at your eyes in the mirror and tell yourself you love yourself no matter what."
This may be the toughest one of all. But trust me, it works. You may not even recognize yourself when you do it. When I did it, I was surprised at the nice looking expression that I had never seen. I felt tears of joy. I certainly did not want to punish myself by picking up the first drink, drug, or addictive behavior. Unconditional self acceptance and love is the key to being clean and sober. When you accept yourself, you will not be jealous or care so much about whether others accept you. You will become less self concious and actually more loveable.
Look at your eyes in the mirror and tell yourself that you love yourself even though you are far from perfect, and even if you feel overwhelmed, hopeless, lonely or sad.
