Burritos as a metaphor for life

When I make burritos, I try to have just enough filling for all of the package of tortillas, but I never put quite enough into the first few so the last few end up fatter.  It occurred to me, as I was overstuffing the last tortillas in the package, that other people approach life differently.  Some people would put too much in the first few and stretch the filling so the last few were skimpy.  And some people would just make burritos until they ran out of something and not care if it came out even.
