The best place I got to work is in Ortigas Center, particularly in Emerald Avenue where time seems to stop. The avenue's sidewalks are a delight to walk in and there isn't much pollution (at least the kind that I don't see) -- not much trash around, less noise and smog from utility vehicles.

This is why I loved sipping hot cups of coco at a small nook opposite this corner building that I sketched one time (left).
