[positive attitude]

The best thing about living a Christ-centered life, however, is how it makes you feel—inside. It’s hard to have a negative attitude about things if and when your life is focused on the Prince of Peace. There will still be problems. Everyone has them. But faith in the Lord Jesus Christ is a power to be reckoned with in the universe and in individual lives. It can be a causative force through which miracles are wrought. It can also be a source of inner strength through which we find self-esteem, peace of mind, contentment, and the courage to cope. I have seen marriages saved, families strengthened, tragedies overcome, careers energized, and the will to go on living rekindled as people humble themselves before the Lord and accept His will in their lives. Heartache, tragedy, and trauma of all kinds can be focused and managed when the principles of the gospel of Jesus Christ are understood and applied.

[great dignity and worth]

[our value]

Such a great article about self worth and self esteem by Elder Cook in January 2014 New Era magazine. So important to realize that our self worth doesn't depend on how we look or how popular we are, etc.

Some quotes from his talk:

The Lord taught that His ways are not the same as the world’s ways and that “my ways [are] higher than your ways” (Isaiah 55:8–9). Following the Lord’s ways allows you to receive eternal blessings and to have the Holy Ghost with you, which can help you feel good about yourself more deeply and consistently than anything the world has to offer. 

When someone seems better at something than you, you may feel like you’re not good enough and that you need to be better in order to be accepted. One problem with this lie is that by tying your self-worth to other people, you’re often comparing another person’s strength to one of your weaknesses.

...loving yourself is not about tooting your own horn or conforming to the world’s view of self-esteem. It’s about being who you are—a unique child of God—and knowing that who you are is a good thing. When you understand your eternal worth and you live in a way consistent with your divine heritage, you will gain a lasting self-esteem that is better than anything the world can offer.
