If you have an outline of your Life Vision, you can follow it or do research that will take you to where you want to be.
A Life Vision helps determine who you really are or who you want to be when you grow up. A very large Life Vision will expand your view of the world. Without a Life Vision you will be in a very small stifled environment.
The larger Life Vision you have for your life, the more opportunities will be presented to you.
If you do not have a vision, you will accept what comes across your path. What comes in front of you, without any input or insights, may not work for you. This would be you settling for what life has to offer without accessing any of your dreams.
