1. To succeed in a career, one must spend a lifetime. ——Leewenhoek
2. Everyone has certain ideals, which determine the direction of his efforts and judgment. In this sense, I never regard comfort and happiness as the purpose of life itself - this ethical basis, I call it the pig pen ideal. The ideals that illuminate my path and constantly give me new courage to face life joyfully are goodness, beauty and truth. ——Einstein
3. A good beginning is half the success.
——Plato
