Length 3 lists always feel better, and my favorite formulation of this is,

  There are only three hard problems in computer science:

  1. Naming things
  2. Cache invalidation
  3. Off-by4. Multi-threading
  -one errors.

My favorite version of this but is like "An engineer has one problem he decides to solve with multi-threading. Now problems. has two he"
