Happiness is the absence of personal problems.

You can remove the idea of personal, the idea of problems, or limit and solve the problems.

Happiness comes from solving problems. The keyword here is “solving.” If you’re avoiding your problems or feel like you don’t have any problems, then you’re going to make yourself miserable. If you feel like you have problems that you can’t solve, you will likewise make yourself miserable. The secret sauce is in the solving of the problems, not in not having problems in the first place. To be happy we need something to solve. Happiness is therefore a form of action; it’s an activity, not something that is passively bestowed upon you, not something that you magically discover in a top-ten article on the Huffington Post or from any specific guru or teacher. It doesn’t magically appear when you finally make enough money to add on that extra room to the house. You don’t find it waiting for you in a place, an idea, a job — or even a book, for that matter. Happiness is a constant work-in-progress, because solving problems is a constant work-in-progress — the solutions to today’s problems will lay the foundation for tomorrow’s problems, and so on. True happiness occurs only when you find the problems you enjoy having and enjoy solving.

Since you can’t avoid problems, just find good problems.
Happiness isn’t everlasting tranquility.
Happiness is solving good problems.

Happiness is not having the best of everything, but the ability to make the best of anything. Happiness is knowing you are doing what you can with what you were given. Happiness is not something that comes to you when every problem is solved and all things are perfectly in place, but in the shining silver linings that remind us the light of day is always there, if you slow down enough to notice.

You don’t achieve happiness by getting rid of your problems – you achieve it by learning from them.

To be happy, one only must be able to confront, which is to say, experience, those things that are. Unhappiness is only this: the inability to confront that which is.

Happiness is the indication that man has found the answer to the problem of human existence: the productive realization of his potentialities and thus, simultaneously, being one with the world and preserving the integrity of his self. In spending his energy productively he increases his powers, he "burns without being consumed.“

A happy life consists not in the absence, but in the mastery of hardships.

The first is to develop a taste for having problems. Behind our urge to race through every obstacle or challenge, in an effort to get it "dealt with," there's usually the unspoken fantasy that you might one day finally reach the state of having no problems whatsoever. As a result, most of us treat the problems we encounter as doubly problematic: first because of whatever specific problem we're facing; and second because we seem to believe, if only subconsciously, that we shouldn't have problems at all. Yet the state of having no problems is obviously never going to arrive.

True happiness occurs only when you find the problems you enjoy having and enjoy solving.

Happiness is a skill you can develop.

Happiness is a how, not a what. A talent, not an object.
