See this Ladder. I can climb it really quickly, but I’m not in a rush.
When you walk into a building, you have the option of either taking the Elevator or stairs. The elevator is much quicker. Fitness folk will tell you that they prefer to take the stairs so that they can “Feel it” in their legs.
How much more when its your building. Walk through every single step, understand every floor. When you get to the top of the building, and you decide to take the elevator daily, nobody can bamboozle you about what happens on each floor. You will know every single step – you walked it for years.
