Answer and Explanation:
One of my experiences that can be cited is the long trips I made, between states, using a travel bus. This source would be important to describe scenarios, in a literary work, since a bus trip allows us to see different real scenarios, since the trip is long and passes through different territories.
Another source would be my family relationship. This would be a very rich source, as family relationships have several good and bad moments and several memories can be explored.
My high school experiences could also be used, the friendships I built, the subjects that I found easy and difficult, the difficulties of socializing and the fun moments.
It is also possible to explore my experiences in the sport (tennis, in this case), my training, difficulties and plans. This can be used as a source to design a character's plans and an activity to which he engages.
Finally, it is possible to explore my experiences when camping or doing some activity in nature, the dangers and the satisfaction of this type of activity.
