The time that passes with goodness will not return with evil; and nothing experienced in life later on can make one day wither or erase one hour of t… - Jens Peter Jacobsen

But for all that, the exultation of the storm was in their young souls. They had faith in the light of the great stars of thought; they had hope fathomless as the ocean. Enthusiasm bore them on the wings of the eagle, and their hearts expanded with the courage of thousands.
No doubt life would in time wear it all out, lull most of it to sleep; worldly wisdom would break down much, and cowardice would sweep away the rest-but what of it?

The time that has gone with happiness does not come back with grief, and nothing the future may bring can wither a day or wipe out an hour in the life that has been lived.

He was first of all a philosopher, but not one of the productive philosophers who find new laws and build new systems. He laughed at their systems, the snail-shells in which they dragged themselves across the illimitable field of thought, fondly imagining that the field was within the snail-shell! And these laws — laws of thought, laws of nature! Why, the discovery of a law meant nothing but the fixing of your own limitations: I can see so far and no farther — as if there were not another horizon beyond the first, and another and yet another, horizon beyond horizon, law beyond law, in an unending vista! No, he was not that kind of philosopher.

To learn is as beautiful as to live. Do not be afraid to lose yourself in minds greater than your own! Do not sit brooding anxiously over your own individuality or shut yourself out from influences that draw you powerfully for fear that they may sweep you along and submerge your innermost pet peculiarities in their mighty surge! Never fear! The individuality that can be lost in the sifting and reshaping of a healthy development is only a flaw; it is a branch grown in the dark, which is distinctive only so long as it retains its sickly pallor. And it is by the sound growth in yourself that you must live. Only the sound can grow great.
