As it is said: A picture is worth a thousand words.
This is because pictures and images are the compartments of our right brain, and our right brain is the portal to our subconscious mind.
Let us say if you were to describe your house in words to someone, do you think it is as good as you draw a picture showing the bedrooms, storeroom, kitchen, bathroom etc?
When you use words, people are using their own interpretation and comprehension. This can end up to be the wrong thing from the intended message.
Don’t get me wrong – words are still required and useful for our daily communication, it is just that in situation where words fall short, pictures could be a better choice.
Occasionally I do create images in my blog post too! But it is meant more for stimulating readers’ right brain.
