Don't get caught up in the identity crisis that has gripped the world. All through history, God's people have been called to be different. If you think the world is happy, look again . Look at the high rate of teenage suicides. We are in a position of blessedness and happiness that the world will never know.
Success breeds happiness.
The reason many people will not pursue meaningful challenges is because they are afraid to fail. Failure causes one to be unhappy. Failure for a Holy Ghost filled, spirit led saint, is just an event in life, rather than a way of life. We can correct our mistakes and go on to be happy in the Lord. See what God did for Daniel.
