Wake up, Lay there and take several deep breaths. Focus on the good feeling of the breathing as you inhale and exhale. Take a nice hot shower. Focus on how good the hot water feels. Focus on how nice your shampoo smells. If you don't like the smell, get rid of it and buy stuff you like. same with the after shave. The clothes you pick up. Look your best. Go out in the world and enjoy interacting with everyone.
I would go to dinner by myself. I would small talk all the staff. Coffee shops, small talk people in line and the staff. Be a good listener. Remember peoples names and their story. Make people laugh. Go do things you love. You will meet people that enjoy the same thing.
