Determination and a conscious effort to stay alive will prevail when the vicissitudes of life visit and weaken you almost to the point of losing hope.
Never lose hope today because tomorrow is in front of you. You hardly know what tomorrow brings, until you are determined to survive today to be alive to see tomorrow.
It is only when tomorrow meets you alive, that you have the opportunity to give life your best shot. And your best shot may just hit your desired target.
So your ability to survive the troubles of today is a function of your determination to see tomorrow.
