Today's side quest is to switch up your practice and studies.
Try a different technique. Try a different way of learning.
We tend to get stuck in our ways and forget that improvement comes from trying new things. Olympic athletes compete in the battle of fractions. They need to be better by fractions of a second in order to win.
To achieve this you need to sometimes change your strategy. Look for an edge.
Today try a new technique or study method and see how it affects your progress. Could be useless or could be what breaks you through your plateau.
