     When we were young, we had dreams and expectations. We imagine things, we keep thinking

about what we want to be, what we want to do, what makes us proud and happy and what we will

become.

     We grew up, and everything seemed like having its own way. We accept our success or failures

and we move on. The change, the need to do the important things, the jobs, the pressures and the

failures, all kill part of our dreams.

     Things have changed, but they cannot really take away the dreams. We still have to dream on, to

realize our desires, our wants, our future, even when we are considered too old for such things. Cornel

Sanders started his business when he was sixty, and started the whole successful KFC business. The

main thing is not the age-whether being too old, or too young, but it is the desire to dream on, and the

courage to realize it.

     Having a dream, taking it to sleep, thinking about it, planning it, and adding all the fun to our dreams

will make us a bit closer to the realization of our dreams.

     Businessmen start with a dream, a simple wish of small restaurant operation, or a huge business of

real-estate(房地产) development, or a training center for English education, or just any other

self-employed money earning fun.

     The ability to dream on is one of the fine qualities of human race that other animals do not have. So

dream on, and put a deadline:make it a giant dream, a small one, an old one, a newfound one, a hobby

related one, a change of life one, a religious one, a stupid one, or just whatever. . . just continue to

dream on. . . Then, Just Go and Do It!
