We sing because we're happy and happy because we sing

A failure is like fertilizer; it stinks to be sure, but it makes things grow faster in the future.

We learn by observation, imitation and repetition.

Expect the best; convert problems into opportunities; be dissatisfied with the status quo; focus on where you want to go, instead of where you're coming from; and most importantly, decide to be happy, knowing it's an attitude, a habit gained from daily practice, and not a result or payoff.

Optimism boosts your energy and focuses your sights on reaching your goals, rather than wallowing in your setbacks.

I would rather fail trying than succeed at doing nothing.

Stop stewing and start doing!
