If, for no reason other than their own beliefs, someone told you ‘only make right turns from now on’ — would you consider that the advice of an advanced navigator? No? Good. Then you can probably now see that ‘positive thinking’ is too smart by half. Get some skill at thinking in general, first. Then you won’t be prey for ridiculous substitutes like this vapid cliché. My idea of ‘positivity’ looks like intelligence being actively developed and enacted. Be some.
