What do all these people have in common? They all died at a younger age than I am now, all having left their mark upon the world (whether they knew it or not).
Even if I live to be a hundred (unlikely), I am still nearly a third of the way through my life. And should I happen to die tomorrow (possibly more likely than the die-at-100 scenario, albeit still fairly unlikely), I do not think I will pop off content with how I have spent my time on this wandering orb.
Small decisions can have big consequences. Not just the consequences you expect, but lots of little and not-so-little ripple consequences spreading out in all directions. And the next thing you know, you’re making Major Lifestyle Changes.
