“What lies behind us and what lies before us are tiny matters compared to what lies within us.” – Henry Stanley Haskins
Haskins observed this in the 1940 work Meditations in Wall Street. The book itself is surprisingly difficult to find, but the sentiment, and others contained therein, remain true – as far as aphorisms can go.
The capabilities possessed in each of us can bring us out of circumstance, can propel us into future endeavors and successes. But first, you must acknowledge that capability and, secondly, perhaps most importantly, you must not be afraid to use it.
