​Wishing for something is different from wanting to reach a goal.
Wishing is like dreaming without providing any action to attain it, whereas the goal deals with motivation and a desire to succeed. 
For example, “I wish for a nice birthday.” This doesn’t tell you how it will happen. In other words, you need to be a little specific.
Consider the following: “I am making my birthday a nice event by doing x and x.” Those x’s will help make the goal a success.
If you apply this thinking to writing (or work), you will see that you’re more motivated to get it done.
I, for one, have set a goal to complete my outline for my novel by making sure to add a line or two a day. Then, I can write the thriller brewing in my head.
I didn’t ask myself for much, but enough to get me wanting to do it so I could reach my goal. The reward is a great feeling you’ve been productive. Then again, a nice scoop of my favorite ice cream wouldn’t hurt.
So far, making a goal has helped me achieve a complete edit for my Young Adult novel, write ten new poems, and allow time for reading. Maybe it can help you.
