I'll go ya one better and say maybe forget your purpose entirely. Not in a negative, nihilistic way, but in kind of a Zenny way. You think Floyd here thinks about his purpose? Well actually it seems like he has decided "my purpose is to care for these people on my route," so maybe that's a bad example for my point. Although it's worth noticing, HE decided that. Which proves, it's totally arbitrary. Meaning is wherever you ascribe it (and probably nowhere else).

Mainly the idea is not to let "purpose" be a logjam that stops you. Life will happen to you regardless. Lately I've been trying to free myself from the endless quest for (please use whiny voice, knit brow earnestly, hold upturned fists close in front of you, and wiggle them slightly while saying) meeeaning. It stymied me for a long time. But it has to be seen for the ego trip it is. It's a "get over yourself" moment. Rein in that fanciful and conceited ego that's always wondering what great and high purpose your magnificent and important soul was cut out for. All that pressure! Letting go of it is a bit of a death (ego death). But jeez what a relief. It frees you to do whatever you want, which ironically is the only way you might actually end up going on to do something worthwhile. (Worthwhile according to you.)
