Oh it's definitely important to "know the limits" of one's
  investigations! I can see how Derrida could lead one into a
  decade of scattering tongue emoticon I'm cautious about taking
  the things I learn and applying them to myself. Very cautious.
  The moment one's study becomes one's lifestyle it becomes, to
  me, a religion; and I try to be very careful of that. *note, I'm
  using the general definition of religion: a pursuit or interest
  to which someone ascribes supreme importance
