If you can keep your head when all about you are losing theirs, and blaming it on you.

Or watch the things you gave your life to broken, and build them up with worn out tools.

If you can talk with crowds and keep your virture, or walk with kings, nor lose the common touch.

This means that sometimes people are going to lose their cool, and sometimes they are going to blame you. You must not lose control just because others do: keep your cool.

This means that when things fall apart, we must do our best to pick up the pieces and begin again. We must do this even if we are tired and worn out and seem to have nothing left.

This means that we should not be followers of the crowd; we must hold to our own morals and values. It also means that even if we are among the rich and powerful, we must remember who we are.
