Try, try and try again
That's how the saying goes.
And so I'll take it to my heart
And will away my woes.
And nothing in life will wear me down,
And positive thoughts will win.
And the challenges that life throws out,
Well, I'll take them on the chin!
And at the end when I am old
And looking to my rest,
I'll be at peace with the life I've lived
And know I've done my best.
