As we travel down life’s road, there are a myriad of possible lives before us.  Each choice we make influences which possibilities lie ahead.  But the life we are given to live is the life that we are in right now.  The future paths we envision may or may not come to fruition.  Now is the time to live our lives, without too much fret for the future.  Tomorrow will have its own concerns; today is the time to live your life.

Al: Ain’t you thinkin’ what’s it gonna be like when we get there? Ain’t you scared it won’t be nice like we thought?

Ma: No, she said quickly. No, I ain’t. You can’t do that. I can’t do that. It’s too much – livin’ too many lives. Up ahead they’s a thousan’ lives we might live, but when it comes, it’ll on’y be one.

― John Steinbeck, The Grapes of Wrath
