Losers will always point to intangible, immeasurable items...
Luck.
Talent.
Circumstance.
They use them as justifications as to why other people are successful...
...and they aren't.
Winners always point at tangible items...
Work.
Time invested.
Effectiveness.
That's how it is now...
That's how it always has been...
That's how it always will be.
You choose daily with your actions which group you are a part of.
