I think there are a few ways for the time a user interacts with an interface to decrease. 1) properly optimize the content. Whenever I create websites, the time it takes for the site to load is a major factor in my design and development process. 2) an easy to use navigation. if a user has to think about how to use the navigation or where to find it, then the navigation is poorly designed.

I would have to say it depends on the situation. When it comes to picking out what to wear, I would say yes, it is sometimes annoying for me to decide on what to wear, especially with the weather always changing. I already let a machine pick the music to play, obviously the choices are within my library.

One way I can think of where I saved time is I saved commonly used HTML code snippets. This way, instead of having to constantly write out code, I can just tap a few buttons on my mouse and voila the code appears. This leads to me having extra time to focus on the content of the site and any debugging I would have to do.
