Really enjoyed your point that many people are being held back simply because they don't know what things are holding them back from achieving their goals - I think this is a vital aspect of success. In my opinion self awareness is one of the first steps in creating a successful life - however someone may define that.
I also appreciated your point about the importance of measuring habits and changing the ones that are not serving you. Although still young, over the past few years I've noticed many of the successful people around me and who I look up to are tracking in some way or another many of the meaningful aspects of their life (tracking fitness, tracking sleep, tracking emotions, tracking business wins, etc.).
