The best thing to improve your state in the current situation that is bad, is by tricking your brain as you said. I had complained about how difficult and stressful my job is. Then i decided to let go away the fear in me by tricking myself into thinking the worse that could happen in the job. I came to the conclusion that i would leave the job as an extreme step, but once i conditioned and prepared my mind to take this step i felt little comfortable with the job. So accepting and overcoming the fear helped me a lot.
Anyhow very nice article to read, upvoted and resteemed and followed
