Goal is what you set before you as an objective to be achieved. It cannot be separated from purpose, it is a determining factor in the way you channel your limited resources. Goals are achieved by strategy and strict compliance. Achievers are known for their penchant for goal setting. No matter how much God-given talent or potential you may have, no matter your drive and zeal, without goal, your realization will amount to nothing. Having a great dream is easy; what is more important is, how do you get it done? Your talent creates the needed platform, but your goal setting will help you get to your desired destination.
The principal thing you need is to discover your talent and the definite purpose of your existence. Any movement in the wrong direction will take you farther from your destination.
