According to Osho, acceptance (contentment) is the seed of true development—evolution of consciousness—while discontent drives outer progress but ends in emptiness and crisis. Eastern sages taught acceptance, and those who lived it (Lao Tzu, Buddha, Mahavir) flowered; yet the Eastern masses only paid lip service and stagnated. The West honestly followed discontent, achieved material success, and now, meeting its futility, turns toward acceptance for inner growth.
Start from contentment to grow real happiness; chasing more and more stuff just leaves you feeling empty.
