Somebody said it so beautifully- “You can’t become what you can’t see.” So we should see our-self in the position we want to be before we reach there.
Stretching the imagination means creating the powerful belief system. It is visualizing oneself to optimum limit of the self desire.
It is to ask our-self to picture our dream life even though we exist completely different in reality. It is to visualize our dream project before we get started. Brainstorming is different thing (even though it is needed) but stretching our imagination is what makes our dreams and projects alive for long term.
Stretching the imagination is the key for success.
