That man is successful who has lived well, laughed often, and loved much, who has gained the respect of intelligent men and the love of children; who has filled his niche and accomplished his task; who leaves the world better than he found it, whether by an improved poppy, a perfect poem, or a rescued soul; who never lacked appreciation of earth’s beauty or failed to express it; who looked for the best in others and gave the best he had.

Robert Louis Stevenson

Live life fully while you’re here. Experience everything. Take care of yourself and your friends. Have fun, be crazy, be weird. Go out and screw up! You’re going to anyway, so you might as well enjoy the process. Take the opportunity to learn from your mistakes: find the cause of your problem and eliminate it. Don’t try to be perfect; just be an excellent example of being human.

Tony Robbins

When you’re smilin’
Keep on smilin’
The whole world smiles with you
And when you’re laughin’
Oh when you’re laughin’
The sun comes shinin’ through

But when you’re cryin’
You bring on the rain
So stop your sighin’
Be happy again
Keep on smilin’
Cause when you’re smilin’
The whole world smiles with you
