First of all, if a person earns a lot of money it means he or she has unique knowledge and experience and people want to pay for these. For example, a good lawyer is often paid a very high salary, because he or she has won many cases and people are ready to pay big money for his knowledge.
A second example is that a salary of a surgeon simpliciter depends on his experience and knowledge and on how many surgeries he has completed successfully. In this case surgeon’s salary simpliciter depends on surgeon’s success.

Second of all, a high salary is in an indicator of a prosperous career and profession. People change their jobs, move from one place to another looking for a more interesting and better paid job. Of cause, some people do not care about salary as long as they like their job, but from my everyday experience and observation I can state that the majority of people who are not satisfied with their revenue would exchange their current job for another one with higher salary.

Finally, money plays, may be unfortunately, a very essential role in our modern life. So, people who earn a lot of money by working hard are considered to be successful.

May be it sounds a little mercenary but I think that success must be encouraged financially otherwise it is not a success.

First of all, I believe that careful planning help a person to analyze his goal more deeply and make realistic goals. He knows exactly what he wants. Taking chances, from the other hand, does not give the opportunity to clearly understand a goal. A person just wants to do something to move forward and he takes risk when there is no need in it.

Second of all, careful planning teaches people to arrange their time more carefully in order to reach their goals. They become more patient and calm. They plan every step. This allows people to find easier way to reach their goals and faster move forward. From the other hand, people who prefer to take risks without planning may spend more time without any improvements waiting for a chance to take. Take sportsmen for example. They exercise a lot before their performance to be in shape, do all their best and improve their previous results.

Finally, careful planning teaches them not to give up, try to find other ways to reach their goals in the case of failure.

To sum up, personally, I think that all people who succeeded in life would agree with me that their success came with the hard work and careful planning.
