The best approach is to design something for a specific user rather than trying to cater to everyone.

I think design is everything. A beautiful product that doesn't function well is, in my view, ugly. The best designs are those that harmoniously integrate form and function, making it impossible to separate the two.

Design should not be for its own sake; it must solve real problems for users.

Design is about creating things for users that work well and delight them.

Designers must be honest in their work, focusing on simplicity and eliminating unnecessary elements to create meaningful products.

In interaction design, it's crucial to avoid reinventing the wheel; instead, adopt existing conventions that users are familiar with.

While specialized models can be effective for specific tasks, the overall trend is towards general models that incorporate learnings from specialized iterations.

Design is fundamentally a problem-solving methodology; the more clarity you provide upfront, the more efficient the design process will be.

Avoid designing by committee; instead, focus on understanding which features will truly enhance your product's value.
