Our Struggle For Existence - Prabhupada 0314

"I shall be happy. My sons shall be happy. My community shall be happy. My nation shall be happy." These are extended selfishness.
Nobody's thinking Kṛṣṇa . . . how Kṛṣṇa will be happy. Everyone is thinking in his own terms: "How I shall be happy, how my children shall be happy, my community shall be happy, my society shall be happy, my nation . . ." This is the struggle for existence. Everywhere you'll find it. This is material existence. Nobody's thinking how Kṛṣṇa will be happy.
Therefore this Kṛṣṇa consciousness is very sublime. Try to understand from Bhāgavatam, Bhagavad-gītā. And hṛṣīkeṇa hṛṣīkeśa-sevanam (CC Madhya 19.170), and try to engage your senses for the service of the master of the senses. Then you'll be happy.
