Do you wish to be invincible? Then don’t enter into combat with what you have no real control over. Your happiness depends on three things, all of which are within your power: your will, your ideas concerning the events in which you are involved, and the use you make of your ideas.

the three factors that seem to have the greatest influence on increasing our happiness are our ability to reframe our situation more positively, our ability to experience gratitude, and our choice to be kind and generous.

Remember, happiness doesn't depend upon who you are or what you have, it depends solely upon what you think.

Happiness depends on your mindset and attitude.

Happiness does not rely on what you have or who you are. It relies on what you think.

Happiness does not depend on what you have or who you are; it solely relies on what you think.

Happiness does not depend on any external conditions, it is governed by our mental attitude

happiness is determined more by one's state of mind than by external events.

Happiness does not depend on what you have or who you are; it solely relies on how you think.

You only have control over three things in your life — the thoughts you think, the images you visualize, and the actions you take (your behavior).

Happiness doesn’t depend on outward conditions. It depends on inner conditions. It isn’t what you have or who you are or where you are or what you are doing that makes you happy or unhappy. It is what you think about it.

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.

Happiness is really just about four things: perceived control, perceived progress, connectedness (number and depth of your relationships), and vision/meaning (being part of something bigger than yourself).

Happiness depends more upon the internal frame of a person’s own mind, than on the externals in the world.
