One's sense of self-worth can either be a source of positive feelings or of distress. Having a deep realization of your intrinsic value protects you from the need to prove to anyone else that you are an important person. Knowing your unlimited value, you are free from the stress experienced by those who lack this understanding.
The Torah view of humans is that we are all created in the image of the Creator. Realizing that "each person is obligated to say, ‘The universe was created for me.'" (Talmud, Sanhedrin 37a) gives you more value than any possible mortal accomplishment. Viewing yourself as a child of the Creator and Sustainer of the universe adds greatly to your sense of personal value.
