There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external (外在的) result or a product that can easily be identified and measured．The worker who gets a rise, the student whose grades improve, the foreigner who learns a new language—all these examples of people who have measurable results to show for their efforts．
By contrast (对照) , the process of personal growth is much more difficult to determine, since it is a journey and not the specific signposts or landmarks along the way．The process is not the road itself, but the attitudes, feelings people have , and their caution or courage, as they meet with new experiences and unexpected difficulties．In this process, the journey never really ends；there are always new ways to experience the world, new ideas to try, new challenges to accept．
