Если тяжело понять всю бесконечность, пытайся понять ее хотя бы наполовину. Славомир Врублевский

"Enthusiasm is the mother of effort, and without it nothing great was ever achieved."
Ralph Waldo Emerson

Jeff Atwood:
I believe a key turning point in every professional programmer's working life is when you realize you are your own worst enemy, and the only way to mitigate that threat is to embrace it. Act like your own worst enemy. Break your UI. Break your code. Do terrible things to your software.

Chinese proverb:
To be uncertain is to be uncomfortable,
but to be certain is to be ridiculous.

Mosher's Law of Software Engineering:
Don't worry if it doesn't work right.
If everything did, you'd be out of a job.
Most people are too busy to have time for anything important.

Eagleson's Law:
Any code of your own that you haven't looked at for six or more months, might as well have been written by someone else. (Eagleson is an optimist, the real number is more like three weeks.)

Emerson's Law of Contrariness:
Our chief want in life is somebody who shall make us do what we can. Having found them, we shall then hate them for it.
