As it is usual for strategists to make a mistake, anybody may fail or make a mistake. However, some people bear the one mistake they made in their minds and thus dont make the same mistake again as others do repeatedly. This means that the former, not to make the same mistake twice, inscribe their first mistake deeply in their memory. We can see this kind of people always live a developmental life. God of love shows us the most beautiful and blessed way of life through the Bible of 66 books. In consequence, to live a happy life, we should take His commands to our hearts and keep them. What then should we do to bear His commands in our minds? First, we should keep close to those who are good minded and set examples to others in all things and follow their examples. Second, we must not let the Word of God depart from our hearts and meditate on it day and night. By doing so, we can keep any untruthful thing away from our hearts. After all, by keeping the commands of God, we can live a life in which everything goes well.
