John Maeda's ten laws of simplicity:
1. REDUCE - The simplest way to achieve simplicity is through thoughtful reduction
2. ORGANIZE - Organization makes a system of many appear fewer.
3. TIME - Savings in time feel like simplicity.
4. LEARN - Knowledge makes everything simpler.
5. DIFFERENCES - Simplicity and complexity need each other.
6. CONTEXT - What lies in the periphery of simplicity is definitely not peripheral.
7. EMOTION - More emotions are better than less.
8. TRUST - In Simplicity we trust.
9. FAILURE - Some things can never be made simple.
10. THE ONE - Simplicity is about subtracting the obvious, and adding the meaningful.
