What can you take from this video into your own work?

First of all, I just want to say that this video was amazing and it was by far the best video I've seen in the business class. I learned so many things that could help me to make my business most successful. Like the gentlemen said «The mind doesn't know what the eyes want». So instead of asking my clients what kind of design they would like for their websites, I should simply offer them a variety of options and this way i'm sure that my clients get what they really want.
