The most treasured and sacred moments of our lives are those filled with the spirit of love. The greater the measure of our love, the greater is our joy. In the end, the development of such love is the true measure of success in life.
Always be willing, even anxious, to help others. Nothing else you do will give you the same genuine satisfaction and joy within because, and I quote, 'when ye are in the service of your fellow beings ye are only in the service of your God' (Mosiah 2:17). Ignoring the needs of others is a serious sin.
The truths of the gospel do not change. If you will follow the Christ, follow his prophet, and follow his Spirit, you will always choose the right. As a result of your wise choices, your testimony will grow stronger, and great blessings of joy, happiness, and peace will be yours.
