#1, #2, #3 change state. #4 is no-op.
Did you just write this extemporaneously? I want to put this where I'll see it at least 3 times a day.
Who would work-hours bear,
To grunt and sweat under a startup life,
But that the dread of something after now,
The undiscovered country to whose bourn
No traveler arrives puzzles the will
And makes us rather bear those ills we have
Than fly to others that we know not of?
Thus time does cause operations in us all,
And thus the native hue of indecision
Is painted o'er with the pale cast of change,
And edifices of great inertia
With this regard their currents turn awry,
And gain the name of action.
