Whoever has character also has his typical experience, which returns over and over again.
Friedrich NietzscheMathematics would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.
Friedrich NietzscheAnd so, onwards... along a path of wisdom, with a hearty tread, a hearty confidence.. however you may be, be your own source of experience. Throw off your discontent about your nature. Forgive yourself your own self. You have it in your power to merge everything you have lived through- false starts, errors, delusions, passions, your loves and your hopes- into your goal, with nothing left over.
Friedrich Nietzsche
