It's actually a pretty long analogy, or maybe more correctly, an extended metaphor, and I think it's quite chilling.
" Jaq. All the world’s a stage,
And all the men and women merely players: 148
They have their exits and their entrances;
And one man in his time plays many parts,
His acts being seven ages. At first the infant,
Mewling and puking in the nurse’s arms. 152
And then the whining school-boy, with his satchel,
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woful ballad 156
Made to his mistress’ eyebrow. Then a soldier,
Full of strange oaths, and bearded like the pard,
Jealous in honour, sudden and quick in quarrel,
Seeking the bubble reputation 160
Even in the cannon’s mouth. And then the justice,
In fair round belly with good capon lin’d,
With eyes severe, and beard of formal cut,
Full of wise saws and modern instances; 164
And so he plays his part. The sixth age shifts
Into the lean and slipper’d pantaloon,
With spectacles on nose and pouch on side,
His youthful hose well sav’d, a world too wide 168
For his shrunk shank; and his big manly voice,
Turning again toward childish treble, pipes
And whistles in his sound. Last scene of all,
That ends this strange eventful history, 172
Is second childishness and mere oblivion,
Sans teeth, sans eyes, sans taste, sans everything."

He uses this elsewhere, in Macbeth's "Tomorrow, tomorrow, and tomorrow" soliloquy and in a couple sonnets.
Michael,
can you explain what you mean by "bored in mind"?
