Roger Staubach's best year in the NFL was about $150,000. Staubach is worth about $600 million today due to smart investing (mostly in real estate) and eventually selling his firm, The Staubach Company, to the Jones Lang LaSalle Partnership.
That doesn't happen by accident. It was the result of smart, well thought-out decisions even if you want to sprinkle in some luck and timing. Staubach wasn't "making it rain" in strip clubs or spending money on ridiculous 'symbols' of perceived wealth like jewelry and fancy cars. Antonio Brown clearly wasn't making smart decisions with his massive fortune, which should have set him up for life.
It's a cliche, but it rings true; It's not what you make, it's what you keep (after saving and investing wisely).
