what is the meaning of If poem by Rudyary Kipling i read it but i don't get what the aruthor trying to say!!! help important plz reply in fast is...

The poem is a father defining for his son the qualities of
a good man. He is setting the parameters or  boundaries for his son and giving him a
goal to achieve.  The poem deals with life's challenges and how to deal with
them.

Stanza one deals with being confident about the
decisions you make and taking responsibility for those decisions.  If others, who cannot
take that responsibility for themselves, react negatively, you should be patient with
them and not reduce yourself to their level by telling lies or dealing in hate. 
However, don't ever believe you are above someone
else.

Stanza two states that it is good to dream, but don't
let your dreams control your life.  It is good to think, but don't just think and not
put those thoughts into action.  You will experience success and disaster in your life,
but don't take them too seriously because  they are not the substance of life; they are
the extremes.  If you hear things you said misquoted or misstated or see things you have
done destroyed, you need to be able to pick yourself up and rebuild them with everything
that you have left in you.

Stanza Three counsels not to be
afraid to take risks and possibly lose everything.  If you do lose everything, don't
talk about it, just start over at the beginning.  When you are tired and exhausted and
your body just feels like it can't continue on, use your mind and your will to command
yourself to "Hold on" and persevere.  Push through
it.

Stanza Four deals with a person's reaction to others. 
You need to be able to talk to big groups of people and yet not let them influence your
belief in what is right, wrong, moral, or immoral.  You need to be able to walk with men
of power and influence and yet not forget the common man and his needs.  You need to
know yourself and your beliefs so well that neither your friends nor your enemies can
hurt you because you know who you are and what you stand for.  People can depend on you,
but don't let them become too dependent on you.  You need to live every single minute of
your life to the fullest.  If you do these things, then the world is yours, and you will
be a good man.
