Which of the rules to live by in "if " are similar to a rule or theme in bud not buddy heres the poem

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 allowance for their doubting too:

If you can wait and not be tired by waiting,

Or being lied about, don’t deal in lies,

Or being hated, don’t give way to hating,

And yet don’t look too good, nor talk too wise;

If you can dream—and not make dreams your master;

If you can think—and not make thoughts your aim,

If you can meet with Triumph and Disaster

And treat those two impostors just the same:

If you can bear to hear the truth you’ve spoken

Twisted by knaves to make a trap for fools,

Or watch the things you gave your life to, broken,

And stoop and build ‘em up with worn-out tools;

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 when there is nothing in you

Except the Will which says to them: “Hold on!”
