At the mercy of life

Life is a journey filled with uncertainties and changes, and we are all at the mercy of it. We cannot control everything that happens to us, nor can we predict what will happen tomorrow. We are at the mercy of our emotions, our circumstances, our luck, and even the elements. But despite this, we must not give in to despair or helplessness. Instead, we should embrace life with courage and optimism, knowing that every challenge and difficulty can bring us growth and understanding. After all, life is a gift that we should cherish and appreciate every moment of it.
