I came across a very good articles by John Greenleaf Whitter.
When Things go wrong as they sometimes will;
When the road you’ve trudging seems all uphill;
When the fund are low and the debts are high;
And you want to smile but you have to sigh.
When all is pressing you down a bit- Rest if you must but don’t you quit.
Success is failure turned inside out; The silver tint on the clouds of doubt;
And you can never tell how close you are;
It may be near but it seems far.
So stick to fight when you are hardest hit- when things go wrong you must not quit.
Wherever you fall down, you should learn to stand up again at the same place.
No worry about failure, treat it as one of the testing way which lead to success.
Most of us, we are so close to success, however we missed it, as we quit slightly earlier.
Be persistent and unshakeable, keep trying until you are successful.
