Make it real.
The Egyptians built everything in the most sophisticated manner, blending art and science perfectly. This way of life carried on even in the afterlife and this single belief resulted in their beyond-life expertise.
While you may look at what they built (pyramids, sphinxes etc…) as purely visual, they saw it as their driver of artistic and technical prowess.
This strong belief in authenticity is about elevation and culture. When I receive something from you, I also should receive a little bit of you too. Everything you make should come with a small piece of you in it.
