14 Whether 'tis nobler in the mind to suffer
15 The slings and arrows of outrageous fortune,
16 Or to take arms against a sea of troubles,
17 And by opposing end them? To die: to sleep;
18 No more; and by a sleep to say we end
19 The heart-ache and the thousand natural shocks
20 That flesh is heir to, 'tis a consummation
21 Devoutly to be wish'd.
25 git commit -q -a -m initial
32 To sleep: perchance to dream: ay, there's the rub;
33 For in that sleep of death what dreams may come
34 When we have shuffled off this mortal coil,
35 Must give us pause: there's the respect
36 That makes calamity of so long life;
