“There are many systems of interaction between brain, body and social world that can get caught in positive feedback loops. Depressed people, for example, can start feeling useless and burdensome, as well as grief-stricken and pained. This makes them withdraw from contact with friends and family. Then the withdrawal makes them more lonesome and isolated, and more likely to feel useless and burdensome. Then they withdraw more. In this manner, depression spirals and amplifies”

“Unless you are genuinely interested in working with someone, don't. It doesn't matter how big an expert they are, or how much grant money the project would bring in. Stay away from things that do not interest you.”

“So, attend carefully to your posture. Quit drooping and hunching around. Speak your mind. Put your desires forward, as if you had a right to them – at least the same right as others. Walk tall and gaze forthrightly ahead. Dare to be dangerous. Encourage the serotonin to flow plentifully through the neural pathways desperate for its calming influence. 

People, including yourself, will start to assume that you are competent and able (or at least they will not immediately conclude the reverse).

Doing so, will not genuinely increase the probability that good things will happen to you – it will also make those good things feel better they do happen.”
