What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him. What he needs is not the discharge of tension at any cost, but the call of a potential meaning waiting to be fulfilled by him.
For some identify happiness with virtue, some with practical wisdom, others with a kind of philosophic wisdom, others with these, or one of these, accompanied by pleasure or not without pleasure; while others include also external prosperity.

There are two things that I want you to make up your minds to: first, that you are going to have a good time as long as you live – I have no use for the sour-faced man – and next, that you are going to do something worthwhile, that you are going to work hard and do the things you set out to do.

There are two kinds of pleasure: one consisting in a state of rest, in which both body and mind are undisturbed by any kind of pain; the other arising from an agreeable agitation of the senses, producing a correspondent emotion in the soul.

Sometimes life hits you in the head with a brick. Don’t lose faith. I’m convinced that the only thing that kept me going was that I loved what I did. You’ve got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking. Don’t settle.
I am grateful for what I am & have. My thanksgiving is perpetual. It is surprising how contented one can be with nothing definite — only a sense of existence. Well, anything for variety. I am ready to try this for the next 1000 years, & exhaust it. How sweet to think of! My extremities well charred, and my intellectual part too, so that there is no danger of worm or rot for a long while. My breath is sweet to me. O how I laugh when I think of my vague indefinite riches. No run on my bank can drain it — for my wealth is not possession but enjoyment.
Poverty is a bitter thing; but it is not as bitter as the existence of restless vacuity and physical, moral, and intellectual flabbiness, to which those doom themselves who elect to spend all their years in that vainest of all vain pursuits—the pursuit of mere pleasure as a sufficient end in itself.
