Disclaimer: I don't own the poem or quote.

 When things go wrong,

As they sometimes will.

When the road you're trudging,

Seems all uphill.

When funds are low,

And debts are high.

And you want to smile,

But you have to sigh.

When care is pressing,

You down a bit.

Rest if you must,

But don't you quit.

 Anyone can give up. It's the easiest thing in the world to do. But to hold it together when everyone else would understand if you fell apart, that's true strength.
