任务型阅读。
     请认真阅读下面短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词。
注意：每个空格只填1个单词。
     Goals are the guides all through our life. We all have goals that we are moving towards and making a
great effort to achieve. This is a good thing. Or can it be bad? How many of us never reach our goals and
yet we have tried so hard and really thought about nothing else? I believe the mistake most of us make is
that we do not focus on our present situation.
     Let me explain. Most of us see our present situation as a stepping stone that we use simply as a means
of reaching our final destination. We don't take time to truly appreciate where we are today and all the great things we already have in our lives. We should focus our attention on the journey and not on the destination, or we will miss the beautiful scenery along the way.
     Let's use our job as an example. Now most of us want a promotion. We have plans to become the
manager or general manager in our companies. Unfortunately, most of us will never reach the goal, but will
watch others achieve our goal instead.
     What we should be doing is focusing on the job we are currently in now. Forget where we want to get
to and just focus on the present. You see, what we can control is our performance in our current job. We
can decide to be the best we possibly can in our current job. Now this may mean further education to have
the skills we currently do not have. It may mean working harder to produce better results than our colleagues. It could simply be a change of attitude, such as stopping complaining and becoming a more devoted and
supportive employee. By doing our current job to the best of our abilities, we in fact give ourselves the best chance of promotion.
     So the best thing for all of us to do to achieve our goals is to just focus on what we have and where we
are now. Do the best and be the best we possibly can in our current situations, and we will give ourselves
the very best chance of reaching our goals in the future. We have heard the old sayings and they are true:
"Rome wasn't built in a day.", "Patience is a virtue", and so on.
Have patience, have appreciation of what we already have, and take time to help ourselves be the very
best we can. Do these things and we will all reach our goals, but more importantly, we will enjoy our life
every day.
