the most universal thing that gives the most success is simply always betting on the best performers. picking the best team/people around you based on your own taste (not what some anonymous crowd thinks) consistently yields good outcomes.​​​​​​​​​​​​​​​​

looking back when i did that it always worked. eventually best performers became not so best and you have to switch to a new (usually much better) ones.

rinse and repeat.

any time i did choose differently - it failed
