“Men at some time are masters of their fates. The fault, dear Brutus, is not in our stars, but in ourselves, that we are underlings.”
From Julius Caesar by William Shakespeare
Plainly said we are (mostly) the masters of our destiny if we would but seize control. Not blame others, or circumstances, biology or upbringing. Rather to a larger extent, recognize that in most cases we are in control. We have the ability to shape the outcome and the choices we make once we recognize that will determine what that outcome will be. .
