What do You Think Are Key Factors For a Person To Be Success

Everybody have different definition about success. Some people judge success just from material or wealth. They used wealth as an indicator to measure a person’s success. For me, successful person is person who can achieve what they want. In my opinion, success is an achievement. An achievement which can’t be achieved by just say “bim salabim” and everything change to be what we wish. We need a commitment and process that we are doing continuously for what we want can be granted.

                To be a successful person, we must think that ourself as a successful person. We must not neglect little succes which we had been doing in the past. For example when we were completed our homework although some people said that thing was nothing but we must think that we have been successful doing the homework

                In my opinion, to be a successful person there are  some things that we can do :

1.       Request

Request to god so that we can be given the ease to get what we want. Request to parent so that pray for us to get what we want.

2.       Believe

When we have been requested to God, we must believe that our request would be granted.

3.       Confident

As difficult as job or task given to us, we must trust and believe ourselves that we are able to finish well

4.       Dare to Risk

To be a successful person, we must dare to face any risk in order to achieve what we want.

5.       Enjoy What We Do

When we enjoy our live, enjoy the job we are doing, so as difficult as our job, it can feel easy to us because we are do it with cheerful and happy

6.       Focus with what we do

When we want to be successful person, we must always focus doing our work, we should not half-hearted in doing our jobs.

7.       Sincere

To be a successful person, in my opinion it needed sincerity. Sincerity  in accepting  all the things that happen.

                Success is everyone’s right, everybody can achieve success as long as he never give up.And success is depend on ourself.
