How was I able to live alone before, my little everything? Without you I lack self-confidence, passion for work, and enjoyment of life--in short, without you, my life is no life. [Written to his wife, Mileva]
Each of you should feel that you have great potential and that, with self-confidence and a little more effort, change really is possible if you want it. If you feel that your present way of life is unpleasant or has some difficulties, then don't look at these negative things. See the positive side, the potential, and make an effort.
