Apple's Human Interface Guidelines simplify the Aqua UI.
Simplicity is the ultimate sophistication. But simplicity is like time. We understand it at a high level, but defining it isn't easy.
The challenge is that simplicity lies on the other side of complexity. Without embracing complexity, the simplicity you produce will be oversimplified; in other words, ineffective. But complexity doesn't have to produce complicated solutions when properly analyzed and presented. We see this all the time in computer applications since software development is about managing complexity.
To achieve simplicity, one needs high performance building blocks that are reliable, predictable, and repeatable. Atoms are a perfect example. But, our lives aren't that simple. In our lives, simplicity means minimizing the introduction of variables, especially random ones. That may sound boring, but when we're bored, it's not complexity we seek, rather, it's randomness.
The Simple LifeGenerally speaking, simpler lives are healthier than complex ones (just ask Elon Musk). So, what does it take to live a simple life?
Simplicity is about living life with more enjoyment and less pain.
To be happy by making every day go as smoothly as possible.
We want to enjoy and consume life instead of working and transforming it.
