Answer:
The first step is to write your wish down on a piece of paper. Then it becomes a goal, not just a wish.
Second, see if your wish is practical. If not, alter it so it is something that you are able to achieve.
Third, Create a plan. How many steps will it take to achieve your goal? Who do you need to help you? What will you each day to make sure your wish becomes true?
Forth, if your wish is not coming true. Start praying :)
