You can tell by the names of the shoe stores that four of them sell athletic shoes. You make note of their locations on the directory in relation to where you're standing and plan a course of travel to take you to them all. In a perfect world, the path you take will not require backtracking. However, sometimes this is unavoidable. In addition, you'll want to stay aware during your travels because you might walk by a department store window that showcases a mannequin wearing your dream shoes.
Life can be like that.
Pursuing our dreams and goals is often the same. Once you've defined them, you'll need to make a plan for achieving them. Consider where you are, where you want to go, and write down all the steps that will take you there. It's important to break each step down into smaller steps that you can wrap yourself around and to give yourself timeframes. For example, your plan for becoming a lawyer should contain more steps than go to law school, graduate, pass the bar, and get employed by a major law firm.
