This is the poem written by G. Linnaeus Banks. Though it's a small one, it touched my heart and I am sure my friends would like it too.

I live for those who love me,

For those who know me true,

For the Heaven that smiles above me,

           And awaits my coming too;

For the cause that lacks assistance,

For the wrong that needs resistance,

For the future in the distance,

           And the good that I can do.
