By expecting to always make money; or to have an always-high hit rate on trades; or to make a consistent, comfortable living from a small portfolio--all of these set us up for disappointment, frustration, and the emotional disruption of going on tilt. They also derail learning, because no one learns best if they aren't enjoying the process and immersing themselves in it. Framing expectations in terms of progress, rather than as lofty attainments, is a great way to sustain focus and positive emotional involvement in the developmental process.
