Cultivating care and concern for others gives rise to a kind of inner strength. No matter what difficulties or problems you face, in this wider context they’ll seem less significant and troubling to you. The inner strength, self-confidence and courage you gain by focussing on others’ needs instead of your own, brings with it a deep, calm sense of satisfaction.
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.
The very purpose of our life is happiness, which is sustained by hope. We have no guarantee about the future, but we exist in the hope of something better. Hope means keeping going, thinking, ‘I can do this.’ It brings inner strength, self-confidence , the ability to do what you do honestly, truthfully and transparently.
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]
Developing concern for others, thinking of them as part of us, brings self-confidence , reduces our sense of suspicion and mistrust, and enables us to develop a calm mind.
