The life of an individual is a constant struggle, and not merely a metaphorical one against want or boredom, but also an actual struggle against other people. He discovers adversaries everywhere, lives in continual conflict and dies with sword in hand.

For all of us in this world life is a continuous fight.

Struggle! To struggle is to live, and the fiercer the struggle the intenser the life. Then you will have lived; and a few hours of such life are worth years spent vegetating.

All life is a struggle for existence. Why should it cease to be a struggle if it spreads among the stars?

The struggle of life is one of our greatest blessings. It makes us patient, sensitive, and Godlike. It teaches us that although the world is full of suffering, it is also full of the overcoming of it.

Life is fragile, yet to obstinately struggle is natural.

The sort of life which I had previous to this popular success was one that required endurance, a life of clawing and scratching along a sheer surface and holding on tight with raw fingers to every inch of rock higher than the one caught hold of before, but it was a good life because it was the sort of life for which the human organism is created. I was not aware of how much vital energy had gone into this struggle until the struggle was removed. I was out on a level plateau with my arm still thrashing and my lungs still grabbing at air that no longer resisted. This was security at last. I sat down and looked about me and was suddenly very depressed.

Life is a perpetual struggle against disruption and chaos.

struggle is the life of sucess

Struggle is everywhere, without struggle no life, and if we want to go on living, we must be ready for further struggles.

We will now discuss in a little more detail the struggle for existence.

In former days the struggle for existence was chiefly a struggle against nature, today it is primarily a struggle against other human beings.

A dozen voices from across the institution told students that while those who lead flat and unremarkable lives may avoid struggle, a well-lived life involves throwing oneself into struggle, that large parts of the most worthy lives are spent upon the rack, testing moral courage and facing opposition and ridicule, and that those who pursue struggle end up being happier than those who pursue pleasure.

I should premise that I use the term Struggle for Existence in a large and metaphorical sense, including dependence of one being on another, and including (which is more important) not only the life of the individual, but success in leaving progeny.
