i doodle so many things all over my papers i couldnt begin to tell you what they mean its usually of things that are on my mind that day it varies all the time one day it could be hearts one day it could be a name i thought looked cool in a type of writing. i try different writing styles like cursive bubble letters many of the sort i doodle alot because i get bored and it keeps me awake in my classes its a very relaxing method. that many students and even adults enjoy doing sometimes it just helps take the edge off and you dont worry about things as much. its a weird thing to have doodling be a relaxer but it does wonders.
