Imagination. Something very important in our lives. Some have very big imagination, but some lack it.
Most scientists lack some imagination, but those who do have imaginations and use them, they're the people who make the biggest most amazing discoveries. I mean, if they didn't have imagination, how the heck would they come up with theories? Theories are basically making stories using the facts that we have. Clues are just as important as imagination. They both work together in order to make the greatest discoveries.

Imagination is important for literally everyone. Singers, they need imagination to write their songs.
Authors, story writers need the biggest imagination ever, kinda like J.k Rowling.
Actors, they need their imagination to imagine the scene they're in to act correctly and convince the watchers that it's real.
Never be afraid to use your imagination a little bit. Live your life, and connect with your inner child. Don't go too far, or you'll forget the reality you live in.

Follow your heart, see where it leads you. You'll find yourself in no time.
