Each one of these things is worth adopting by itself, if adopting all of them at the same time is intimidating.
Item 5 can be interpreted in more than one way, though, so I think it's worth digging into. At a fundamental level, with virtually no tradeoffs, it's important not to be crowded by dirty dishes while you cook. If you're worried about your elbow bumping a water glass while you chop onions, or if you have to reach around a dirty mixing bowl to find the garlic, it's going to slow you down, both physically and mentally. Keeping your workspace tidy pays back every second many times over.
Taking "clean while you cook" even further, you can try to save time by scrubbing pans and bowls as you are finished with them. This is extremely appealing for busy people, but how feasible it is depends on what you're making, how much work and attention it requires, and how fast you are. It's a rare triumph for me if I can put three dishes on the table with no dirty dishes in the kitchen. I've done this, but much more often, I've messed up dishes when my attention got hijacked by scrubbing a pan that I could have left for later. If you feel rushed or stressed while cooking, you can give yourself breathing room by getting the dirty stuff out of the way in the easiest possible manner, even if that means stacking it to clean it later.
