Most of us don't leave enough margin in our lives. We live too close to the edge. This motivational maxim is a good one to put in your car. If you slow down a little bit, it could save you a lot of time.
Many who have accomplished great tasks have done so by deciding not to give up.
As Scripture says,
"Let us not be weary in well doing: for in due season we shall reap, if we faint not."
Persistence is a Biblical trait.
"FAITH makes the difference between
a miserable ordeal or a memorable adventure, between exhaustion or excitement."
Another quotation like the above was told to me by a preacher friend.
He said, "I am tired IN the work, but not tired OF the work."
