Before you get your brain wrapped around the axle, you can relax, it's just a trick question.   There are so many variables involved in being able to answer this question you'd just be jumping the gun.  However, many of you reading it may already be half-way through describing a plethora of examples of how "other" people have or use too much.  It can be a bit of a knee jerk reaction to assume that the "much" in question is monetary when for all intents and purposes it could just as easily have represented "love".

So, now, replace the idea "how much" with "how much love" and what is your answer?  How about "energy" or even "patience"... does your idea of "too much" change?  If so, how so and why?  Perhaps these are the better questions to ask, as they lead us to opening our minds instead of closing them shut like well oiled steel traps.

Then, maybe when we realize that the answer to "how much" really depends on our own ideas and desires then it can become clear that just like "love", or "energy" or even "patience" the maximum threshold for "how much money" we consider "too much" is also self-regulated. 

If you find this true than I encourage you to spend a little time stretching your own limits and allowing for the possibility that there is no such "thing" as too much.  Life provides you as much of anything; love, patience, energy, and even money as you are capable of accepting.
