I have always had a keen interest in architecture since my youth only because I saw it as a visual art that I could not master. One draw back was that I was never good in math but architects are visual thinkers who see four walls and a roof and I am not wired that way.
I would sit down many times and try to sketch a building but get frustrated because I was sketching buildings that are still square boxes. What I see now in the world of architecture, is sweeping curves and organic shapes that are quite fascinating to look at.
Architecture is a public art form. Everyone can see it and form an option on it right away. Other forms of visual art remain hidden behind gallery walls and museums that no attends.
By walking into a building, you have personal tour of the architect's thinking process. You can see what works and what does not. If you have no time to look around, no worry. The building will still be there tomorrow and for years to come.
