To accomplish your goals, however, you need to know how to set them. You can't simply say, I want and expect it to happen. Goal setting is a process that starts with careful consideration of what you want to achieve, and ends with a lot of hard work to actually do it. In between there are some very well defined steps that transcend the specifics of each goal. Knowing these steps will allow you to formulate goals that you can accomplish.
The process of setting goals helps you choose where you want to go in life. By knowing precisely what you want to achieve, you know where you have to concentrate your efforts. You'll also quickly spot the distractions that can, so easily, lead you astray.
