Humility

Two important things I've been trying live by recently (both quotes from the same talk by Elder James B. Martino)

1.) "We may never know in this life why we face what we do, but we can feel confident that we can grow from the experience.

Now, I realize that it is much easier to look back when a trial is over and see what we have learned from our experience, but the challenge is to gain that eternal perspective while we are going through our tests. To some, our trials may not seem great, but to each of us who are passing through these experiences, the trials are real and require us to humble ourselves before God and learn from Him.
...a small amount of pain now will protect them from possible pain and suffering in the future. Our Father in Heaven knows the end from the beginning. We need to follow the example of the Savior and trust in Him."

2.) “I believe the Savior is telling us that unless we lose ourselves in service to others, there is little purpose to our own lives. Those who live only for themselves eventually shrivel up and figuratively lose their lives, while those who lose themselves in service to others grow and flourish—and in effect save their lives.”
-President Thomas S. Monson
