Lost Time
When I was a child I thought time was something stored in a clock If we wanted more of it, all we had to do was turn a key to the right every eight days. Once I turned the key to the left and lost what seemed like forever locked in my room.
In my opinion, room can both be a physical room or a mental one. The mental room we create is much like the physical one, but it's different for every person. And about time, i can say the same thing. How we spend time in our mental room isn't the same as when we spend time in the real world.
Time is measured by routine.
