Focus on what you want and take action in that direction. Make a real effort and do your best. If you put energy into a wish and a goal long enough, it will materialize at some point. You may encounter difficulties. If one thing is really important to you, you will overcome it. Make sure you keep focusing your energy on the goal and the solutions to your wish (not too much on the problems) and you have a good chance of achieving your goal.
It goes without saying that not every wish is achievable. Many want to become president. It takes a lot to achieve extremely high goals. I’m talking here more about things that people achieve every day and wishes that you really want or that improve your quality of life or that you have great experiences with.
