I don't know what comes after this life, but I know it must be one of two options - either I get another life, or I don't.
If I was guaranteed another life, why am I rushing in this one? I have time to start golf sooner, learn the piano and ride a horse, study the arts and travel. Knowing I have lots of time ahead, in this life I would slow down.
And if I was told "Sorry, this is all you get", would I still spend this life rushing from crisis to crisis, working everyday in constant pursuit of more? Nope. I would read more books, spend more time with friends and family, and do things I love. In this life I would slow down.
Wow. I bounded the problem and got the same answer.
We are all one decision away from a completely different life. Slow down and get a headshot.
