During the middle ages, monks made little illustrations or notations in the margins of manuscripts. The technical term for this kind of doodling is marginalia. It's not the main illustrations. They are doodles done in the margins. 

These manuscripts are somehow connected to sketchnoting because they are books written by hand 'manu' means hand; 'scriptus' means to write. They are not printed books."

You can incorporate specific characteristics about these provocative drawings to take your visual metaphors to the next level. 

1) Blend to drive attention. 

Today, we use a highlighter marker to draw attention to a key piece of text we are reading. But back in the Middle Ages, when they wanted to highlight something, they drew a little symbol called the manicule. Which in Latin means 'little hand.' As you can see in these drawings, they were not just hands many times. They blended these hand symbols with something else to add an extra hook to highlight and...

 One of the most common mistakes in visual thinking is making visual maps or sketchnotes in which everything we draw has the same size.

A couple of years ago, a video by Dave Gray reminded me of the way the Egyptians represented their gods, and this is a great tip because most visual maps fail due to the lack of hierarchical levels. This means that when you apply visual thinking through a map or a sketchnote and all the drawings have the same size; we communicate that everything has the same importance. If everything has the same visual importance, it will be difficult to attract attention to those important parts of your map.

That's why the Egyptian perspective could help with hierarchy in your visual thinking.

The main characteristic is that Egyptian figures were depicted of sizes based on importance and not on their distance from the sculptor's perspective. For instance, the Pharaoh would be depicted as the largest figure in a wall no matter where he was situated, and a...

Accepting imperfection is essential for creating compelling visual thinking.

Nowadays, people post content with a lot of makeup. Think about the content that you see or that you post on social networks.

How many of the photos you post have previously passed through your filter. What are your main criteria to apply those filters? Probably perfection. They are all moments of perfection. The perfect photo, the perfect moment, the perfect occasion to show something. The perfect mess. Even those images that show messy situations, if you pay attention, are a perfect and neat mess.

For this reason, one of the most significant restrictions we impose on ourselves is perfection. The consequence of this is the fear of not meeting those perfect expectations.

Let me tell you something:

Good visual ideas are going to come from a context of chaos. Any creative process is born out of...
