QUOTE : It's a lesson I'm trying to learn from him, this living squarely in the present. I am a planner and a worrier. I torment myself by mentally replaying my past mistakes, wishing I'd been smarter, wishing I'd been stronger, wishing I'd made different choices. I live too often in the realm of WHAT IF. I also expend time and mental energy continually trying to anticipate what sort of crouching tiger might be hiding around the next corner. Nathan's default seems to be to take life as it comes and contend with tigers if and when they appear.
