Who steals my purse steals trash; 'tis something, nothing;
'Twas mine, 'tis his, and has been slave to thousands;
But he that filches from me my good name
Robs me of that which not enriches him,
And makes me poor indeed.
- Shakspeare, Othello
The Key to happiness is not being rich; it's doing something ardous and creating something of value and then being able to reflect on the fruits of your labor.
- Arthur Brooks, The Battle
