Put Your Whole Ass Into It

“Death is a once in a lifetime opportunity.”
To The Chemical Buddha, everything was a once in a lifetime opportunity. Because even if the same opportunity came around twice, he was never the same person both times. So he saw each moment as unique and special. And he always tried to take advantage of every situation he could. Of course, doing that often meant he was too busy or already locked in to a choice when a seemingly better option would come his way. When that happened, he’d try to do both and would usually just end up doing both of them really, really half-assed. But he got to do them both, and that was all that counted in his mind. Because he knew he would be different the next time and therefore have a second chance to half-ass it.

Do you jump at opportunities or wait and think things through? What are the benefits and drawbacks of jumping? What are the benefits and drawbacks of thinking things through?
