Imagine suddenly you no longer exist, poof, from one day to the next there is no more you.
What if you knew that this day would come in a month?
What if it wasn’t for another year?
Or in 5 years?
Would you spend your remaining time differently than you do now?
If so, why aren’t you already doing it?
If I knew there was nothing after next week, I’d keep doing what I do, but harder.
