I don't know what I got into, but this was the theme I got from joining a Photography Contest. "Calm amidst the haste and rush"

PS. The contest is not over, I'm still gonna take my shots.

Oh well, will you guys just help me out? I'm thinking of a concept on weather to shoot things scripted, or just go on the street and find something. 

I was thinking of several concepts, and I don't know if it'll work.

1. A traffic enforcer doing his daily duties on managing the traffic?

2. Chess players doing there thing in the park?

3. Students studying in restaurants? 

What's the best idea?
