It doesn't matter if you're on the go, chilling in a hottub, running a maranthon or flying in a private jet, products need to work as you expect. My personal goal is to give the perfect experience of products for all people. Everywhere and anytime. 3 things were I'm focused on while working on a project:
Don't put out any kind of nonsense into your project. Only put in the essentials. This will speed up the the flow of the user and will work efficient for the user.
Always think by yourself: "How can the user achieve X as fast as possible". This can make a major difference in how your design will look and feel.
When you work for clients or different kinds of a target audience, you need to make your product work for them. This means you have to be adaptable in each situation. Don't push your own taste into a product that needs some other flavor.
