few lines from the poem 'If' by Rudyard Kipling.....this is one of the best poem which beautifully explains the power of ' Hold On ' ...........

If you can make one heap of all your winnings

And risk it on one turn of pitch-and-toss,

And lose, and start again at your beginnings

And never breathe a word about your loss…

If you can force your heart and nerve and sinew

To serve your turn long after they are gone,

And so hold on where there is nothing in you

Except the Will which says to them: ‘Hold on!’
