2. Focus on the present, not yesterday or tomorrow.

When one door of happiness closes, another opens, but often we look so long at the closed door that we do not see the one that has been opened for us.
Helen Keller
The foolish man seeks happiness in the distance, the wise grows it under his feet.
James Oppenheim

3. Don’t forget to be grateful.

Man is fond of counting his troubles, but he does not count his joys. If he counted them up as he ought to, he would see that every lot has enough happiness provided for it.
Fyodor Dostoevsky
We tend to forget that happiness doesn’t come as a result of getting something we don’t have, but rather of recognizing and appreciating what we do have.
Frederick Keonig
Let us be grateful to people who make us happy, they are the charming gardeners who make our souls blossom.
Marcel Proust

4. Help someone else find happiness.

Since you get more joy out of giving joy to others, you should put a good deal of thought into the happiness that you are able to give.
Eleanor Roosevelt
Thousands of candles can be lighted from a single candle, and the life of the candle will not be shortened. Happiness never decreases by being shared.
Buddha
If you want happiness for an hour — take a nap.
If you want happiness for a day — go fishing.
If you want happiness for a year — inherit a fortune.
If you want happiness for a lifetime — help someone else.
Chinese Proverb
Happiness is like a kiss. You must share it to enjoy it.
Bernard Meltzer

5. Get rid of a couple of your less valuable desires.

If thou wilt make a man happy, add not unto his riches but take away from his desires.
Epicurus
You can never get enough of what you don’t need to make you happy.
Eric Hoffer
That man is richest whose pleasures are cheapest.
Henry David Thoreau

6. Do what you like to do.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
Albert Schweitzer
Happiness is not in the mere possession of money; it lies in the joy of achievement, in the thrill of creative effort.
Franklin D. Roosevelt

7. Or at least do something.

Action may not always bring happiness; but there is no happiness without action.
Benjamin Disraeli
Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.
Mark Twain
