The key to slowing down life is variety. As a child every year was distinctly different: even today I can remember each school year because I had a different teacher, a different homeroom, etc. As an adult each of my jobs has been on average 4-6 years. Each job is a bit of a blur; the years at the same job are difficult to distinguish from each other. To slow down time, make sure you do different things each year: trips, projects, roles at work, etc. The more your mind can distinguish the years, the slower time seems to move. Try it - it works!
