Being altruistic does not mean totally rejecting our own interest or neglecting ourselves, this is a misunderstanding. In fact, the kind of altruism that focuses on the well-being of others arises from a very courageous mind, an expansive attitude and a strong sense of self confidence – so much so that the person is capable of challenging the self-cherishing and self-centeredness that tends to rule our lives.
When our intentions toward others are good, we find that any feelings of anxiety or insecurity we may have are greatly reduced. We experience a liberation from our habitual preoccupation with self and paradoxically, this gives rise to strong feelings of confidence.
If you develop a pure and sincere motivation, if you are motivated by a wish to help on the basis of kindness, compassion, and respect, then you can carry on any kind of work, in any field, and function more effectively.
