All a Man Can Do by Tom Rush

"All a Man Can Do" by Tom Rush starts off with a young man saying goodbye to his parents, young and fresh, embarking on his life. In the end,

It doesn’t seem so long ago, I hitched down to New Mexico
I kissed my mama, I saw my father’s stone
Friends are gone or out or touch, but nothing seems to change that
much
The desert’s hot the sky’s still blue, I’m getting by still making
due
Take your chances take your shot, cause 50/50’s all you got
Make each day the best you can, that’s a line I understand
Live each moment like your last, cause life goes by you so damn fast
Make a promise and keep it true, cause that is all a man can do

What this makes me think of is that we grow older, we all experience hardships and loss. The unwise feel sorry for themselves and feel injustices have been done to them. The wise recognize that it's part of the cycles of life, and are able to maintain their sense of wholeness and keep on going through life, keep on seeing the beauty in life.
