That's what I am. I go out for a walk every once in a while and observe the outside world. As a bystander, I must first choose a destination, which can be in the same city or a little further away. From the moment I went out, I took it as part of my trip, including taking a bus-going to the station-walking to my destination, and then finding some entertainment for myself, such as drinking something delicious and eating snacks, and then staying in a place. If it is a short trip, you can do it with that kind of exploratory mentality, which will be very interesting. On the way, what I do most is to find the bright spot. I often find some interesting things that people don't notice, and then shoot them and publish them, so as to drive people around me to look for them with you, and then you can read their publications to entertain yourself. I have the habit of drawing. I have a painting software installed in my mobile phone, which is a little professional, but it is not difficult to get started. In a quiet or monotonous place, I will take out my mobile phone to draw in my spare time, which can perfect a long work or draw some sketches at will. Of course, modern smart phones are actually enough to spend most of your life. Actually, having a cell phone should be enough to talk.
