A closed mouth gathers no feet. Silence is wise if we are foolish, but foolish if we are wise. The early bird gets the worm, but the early worm gets eaten. In the winds of change, keep the fire within. Even the boldest zebra fears the hungry lion.
Excuses are the easiest things to manufacture, and the hardest things to sell.
Even the smallest candle burns brighter in the dark. Never try to leap a chasm in two jumps. Water which is too pure has no fish. Laugh alone and the world thinks you're an idiot. Artificial intelligence is no match for natural stupidity.
