Quantify and track your sleep, eating, exercise, reading, mood, energy, etc. Increase the good, decrease the bad. Push yourself. Look for correlations. Tweak variables. Introduce new ones. Discard what doesn’t work.
Remember the Peter Drucker dictum: “What gets measured, gets managed.” Focus on concrete behaviors (“Do 50 dips every morning.”) over goals (but have concrete goals (“Run 26.2 miles.”)).
Caveat: Information does not necessarily lead to action [Fogg].
