     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.  

     In order to grow, to travel new roads, people need to have a willingness to take risks, to face the

unknown, and to accept the possibility that they may "fail" at first. How we see ourselves as we try a

new way of being is necessary for our ability togrow. Do we see ourselves as quick and curious? If so,

we tend to take more chances and be more open to unfamiliar experiences. Do we think we're shy and

indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we are slow to

adapt?(适应)change or that we're not smart enough to deal with a new challenge. Then we are likely to

take a more passive role or not try at all.  

     These feelings of insecurity(不安全)and self?doubt are both unavoidable and necessary if we are to

change and grow. If we protect ourselves too much, then we stop growing. We become trapped inside a

shell of our own making.
