Success means that a person achieve whatever he desires, aims. Success can be achieved if there is an opportunity, without any opportunity success will not be achieved. Some people may think that success has related with opportunity only. As far as i am concerned, without careful planning success cannot be achieved. I have some reasons for my openion. Planning means that a person giving his thoughts some direction, and by following these direction he can achieve whatever he wants. For example if a school going child wants to achieve his goal of being selecting by well known college ,university. He will carefully plan to study and put his efforts. He will plan all of his activities to be acted upon i-e how much time he will spend on completing assignment, he will do group discussion, how much time he will spend on playing, watching T.V. The whole plan will be a result in high grades and thus child with his careful planning will be able to succeed in achieving his aims. Similarly, a book publishing company decide to organize a book exhibition in an open ground. They get the opportunity to organize it in the wellknown open air ground, but at that day the unexpected rain starts. If the book publishing company will have some careful planning they will already plan to handle the condition by arranging it in indoor available area. If they didnt have any plan then their whole activity will be result in zero and they will not be succeed in their aim. Therefore, i conclude that chances require to succeed in life but if there is no careful planning to attain these chances in useful way then no success will be possible. Thus, careful planning is require to succeed in life.
