（45）Generally speaking, those who have good motives do their duties well. For example, parents work hard from early morning till late at night because they want to support their families. Students study diligently either to rank top in their class or to be prepared for their future success.
（46）On the other hand, people do things evil because they have evil goals. For instance, the motive for getting money without hard work makes a pickpocket steal a purse. To fulfill his evil desire, a robber grab others’ belongings, and a murderer can kill an innocent person. These wicked motives are the kind that people need to get rid of because they hurt others.
（47）It is often easier to have ideals than to carry them out.
（48）Effort and persistence are necessary for the realization of ideals.
（49）Once the goal is determined, we must create opportunities to reach it. Work hard and be patient after your goal is set. Try your best to make your life happen in the way you wish to see it. It is those who set the right goal and stick to it long enough will finally achieve it.
（50）Living without an aim is like sailing without a compass. When ideals are gone you may still exist, but you have ceased to live.（虽生犹死）
