"What are your concerns in life at your age? Some of you have had questions on your minds about schooling, employment, marriage, and other general directions in life—about how to best fulfill the expectations of yourself as well as the expectations the Lord has for you.
If I were your age and thinking about life and its meaning, there is one characteristic that I would strive to develop. That characteristic is to have a positive attitude. I am a great believer that what you and I think about will ultimately come to pass. I believe if we think about committing a sin long enough, we will find ourselves entangled in that sin. I believe if we think about what it takes to be successful long enough and if we are willing to discipline ourselves to the principle of success, we will experience success. Yes, I am a great believer that “as [a man] thinketh in his heart, so is he” (Prov. 23:7).
I have learned that I really do have control to a great degree over my circumstances. If I don’t like them, I’ve found there are certain things I can do to change them. If I want to move to higher ground, if I want to have more positive experiences, I must think about life in positive terms, not dwell on the negative."
(M. Russell Ballard, “Go for It!,” New Era, Mar 2004, 4)
