“Affordances define what actions are possible. Signifiers specify how people discover those possibilities: signifiers are signs, perceptible
signals of what can be done. Signifiers are of far more importance to designers than are affordances.”

“A brilliant solution to the wrong problem can be worse than no solution at all: solve the correct problem.”

“To really change the world, we have to help people change the way they see things. Global betterment is a mental process, not one that requires huge sums of money or a high level of authority. Change has to be psychological. So if you want to see real change, stay persistent in educating humanity on how similar we all are than different. Don't only strive to be the change you want to see in the world, but also help all those around you see the world through commonalities of the heart so that they would want to change with you. This is how humanity will evolve to become better. This is how you can change the world. The language of the heart is mankind's main common language.”

“The problem with the designs of most engineers is that they are too logical. We have to accept human behavior the way it is, not the way we would wish it to be.”
