I don't have a set number of comments that I try to do per day. It's normally just based on what time and energy I have available.
I do the same, when i have time, which is usually when i'm on holidays i spend almost every hour of the day just reading and commenting other people content! When i have to study, like i lately had i just stick to 2 or 3 people, sometimes i don't even comment anyone's content tbh, quality is much more important than quantity, i can't understand those people that just comment 1 phrase and that's it, and even worse are the spammers!
Good to see you are taking some breaks to enjoy life! Wish i had the time, i have 1 week vacation and then 1 full month of exams after exams, i'll probably be almost gone for 1 full month :(
Sorry to hear you're so slammed with exams and such. I hope you're able to get a break once you're done. It's important to have time just to relax and recharge. Thanks for stopping by. I'm honored to be one of the few to get a comment from you! :)
