Get the IFmug. IF by Rudyard Kipling starts -
If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you,
But make allowances for their doubting too;
......and ends ...
Yours is the earth and everything that's in it
And - which is more - you'll be a man, my son.
If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you,
But make allowances for their doubting too;
......and ends ...
Yours is the earth and everything that's in it
And - which is more - you'll be a man, my son.
