Get lost - my advice today.
There are various methods to do it, but I do it this way.
Getting my camera I head out of my house to the next cab or bus stop to take a taxi for 10 minutes or the bus for about five stops. Getting off the transport utility I take a left and start to walk. Strolling aimless through the town until I see someone smiling at me. Then I turn the next right. I do this until I find a coffee shop. There I stop and observe.
Looking around what is interesting and where to get an overview I head for the next hill, ladder, roof or something alike. There I rest about 10 minutes and start looking what unfolds before me.
Today I reached Grant Road in Mumbai with this approach.
