first and second posts of the series!
Try being a critic for a day or two. Pick a specific kind of establishment like Italian restaurants, vintage movie theatres, tattoo parlors, etc. and map out several along a route. Then go to each one you see and try them out. When you get home, go on yelp or some other review website and write a critique for each one.
Several years back in my high school days I was really in to playing Dungeons and Dragons so I mapped out every store within 50 miles of my town and created the fastest route possible to get to each one within the day.
I had a blast! It was a ton of fun trying to find each store and then exploring the different aspects of each one. I didn't buy anything that day but my friends always knew to ask me what the best place was to go to get any kind of D&D product.
I did the same thing for coffee shops when I visited Seattle a few years later. If you want to know, the best coffee I had was at Caffe Ladro in the Fremont area. Although Pergolesi's in Santa Cruz is still my all-time favorite.
So go ahead and try it yourself. You may just become a critic in a brand new field!
