Edgar A. Guest says it best with the words of this powerful poem. It is worth reading and putting somewhere close so you can read it again sometime in the future.
When things go wrong, as they sometimes will,
When the road you're trudging seems all uphill,
When the funds are low but the debts are high,
And you want to smile but you have to sigh,
When care is pressing you down a bit...
Rest if you must, but don't you quit!
Life is queer with its twists and turns,
As every one of us sometimes learns,
And many failures turn about
When we might have won had we stuck it out.
Don't give up though the pace seems slow...
You may succeed with another blow.
Often the struggler has given up
When he might have captured the victor’s cup;
And he learned too late when the night came down,
How close he was to the golden crown.
Success is failure turned inside out...
And you can never tell how close you are
It may be near when it seems so far.
So stick to the fight when you’re hardest hit
It’s when things seem worst that you must not quit.
The following words from Eugene Peterson's paraphrase of the Bible also make a lot of sense. "But don’t quit. Don’t cave in. It is all well worth it in the
end. It is not success you are after in such times but survival. Be
survivors! Before you’ve run out of options, the Son of Man will have
arrived." - Matthew 10:22-23 (The Message)
