Einstein often mentioned curiosity. For example, he was quoted as saying, "I am neither especially clever nor especially gifted. I am only very, very curious."
Times come along when curiosity is all we have, and in the absence of love; our faith and hope may be resting upon it. The world is full of interests within incredibly diverse aspects; but only for interested people. Hedonists on the other hand, accept the status quo or you might say, their current level of whatever it might be. They do not prioritise learning.
People need continuing motives to keep things going, and with sufficient energy. Growth for its own sake can be reason enough. Pleasure categorically suggests stagnation.
At times we get stifled by people. Maybe promotion at work is unfairly blocked. The world will always produce blocks of various manifestations, but if personal growth runs alongside these external vulnerabilities, life is more manageable, because in reality, our inner aims are the only reliable deals on the table.
