When you have a desire but not the faith that you can achieve it, then you call it daydreaming.

When you have a desire but not the faith that you can achieve it, then you call it daydreaming. 

When you do not know yourself, or your potential, you have no faith or confidence in your dreams. But once you have faith and confidence in your dreams, they are no longer daydreams!

.- Gurudev Sri Sri Ravi Shankarji
