Whose woods these are I think I know.
  His house is in the village though;
  He will not see me stopping here  
  To watch his woods fill up with snow.

  My little horse must think it queer
  To stop without a farmhouse near
  Between the woods and frozen lake
  The darkest evening of the year.

  He gives his harness bells a shake
  To ask if there is some mistake.
  The only other sound’s the sweep
  Of easy wind and downy flake.

  The woods are lovely, dark and deep,
  But I have promises to keep,
  And miles to go before I sleep,
  And miles to go before I sleep.

Sleep! I say sleep. Get that rest and damn that horse. :-)

Edit: I took me 4 years to learn HN carriage returns! :-(

- Founder <-> founder resentment

- Founder <-> investor resentment

Those 3 causes are far above everything else, in cases I've seen. Even higher than running out of money.
