Success is not the key to happiness. Happiness is ...

It were a real increase of human happiness, could all young men from the age of nineteen be covered under barrels, or rendered otherwise invisible and there left to follow their lawful studies and callings, till they emerged, sadder and wiser, at the age of twenty-five.

Oh, if I had been loved at the age of seventeen, what an idiot I would be today. Happiness is like smallpox: if you catch it too soon, it can completely ruin your constitution.

You get to a certain age where you prepare yourself for happiness. Sometimes you never remember to actually get happy.

I learned from a very young age that if I pursued the things that truly excited me, that they would reward in more important ways, like happiness.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Age does not protect you from love. But love, to some extent, protects you from age.

Each moment of a happy lover's hour is worth an age of dull and common life.

Old age is like everything else. To make a success of it, you've got to start young.

Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.

Have regular hours for work and play make each day both useful and pleasant, and prove that you understand the worth of time by employing it well. Then youth will be delightful, old age will bring few regrets, and life will become a beautiful success.

I'll tell you, there is nothing better in life than being a late bloomer. I believe that success can happen at any time and at any age.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

Common sense is the collection of prejudices acquired by age eighteen.

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Wisdom doesn't necessarily come with age. Sometimes age just shows up all by itself.
