What’s better to have, great imagination or lots of knowledge?

After thorough thinking and comprehension of this question, I have come to the conclusion that you can't really have one without the other, you can't honestly say that imagination is only important in a man's life or having all forms of knowledge alone is the way forward. Ben Carson the best neurosurgeon ever had was once dull boy who could not even read or learn anything but with the help of his mother and determination he turned be the best in his field. What does this mean to me, that even if he had all kinds of imagination and didn't have a little bit of knowledge about what he was getting into, he would have failed. One who has an imagination of the future must have the ability/the mindset and the knowledge of how to carry out the task ahead, he must be able to plan how it is going to work out, if not failure will be the order of the day. One who has only knowledge but don't know how to use this gift to think up better ways for a situation is in a limbo. I would prefer to work hand in hand with them.
