1. Start with People: Focus on the real needs and experiences of the people you're designing for, so the solution truly works for them.

2. Make it Accessible: Ensure everyone, regardless of ability, can use and enjoy the design without barriers.

3. Think Sustainably: Create with the planet in mind, using materials and methods that reduce harm and promote long-term impact.

4. Plan for Growth: Design solutions that can evolve and adapt as needs change over time.
