Too much planning?

An enlightening quote from Along Came Polly by Ben Stiller and Jennifer Aniston:

Ben's father (in the movie) said:
It's not about what happened in the past, or what you think might happen in the future. It's about the ride, for Christ's sake. There is no point in going through all this crap, if your are not going to enjoy the ride. And you know what... when you least expect something great might come along. Something better then you even planned for.
