Focusing on your dreams, and speaking them into existence help you to reach your goals. If you can see it in your mind, then you may have one more piece to reach the top.
If nobody believes in you, you need to be able to believe in you to hit your mark. All dreams come from within. Making that dream into a reality is where the work comes in. However, if you can’t see it for yourself, then it takes away from your ability to create the reality.
Bottom line: believe in yourself.
