Summer vacation: after reaching a difficult milestone or any time in between during summer?

Hi! I bet everyone here is working really hard and have serious plans ahead for the whole summer. It’s an app for detailed habits, health, symptoms, and meds tracking. Pretty much for everything that is related to your physical or mental health and every daily factor that can affect you. I'm currently working on a serious project, called Effecto, myself. Check out our upcoming PH page: www.producthunt.com/upcoming/eff... But let's put working things aside and talk about summer vacation. How do you see it? Do you go on vacation because it's summer or you're only taking a break after you get some serious stuff done? Why? I myself already used some of my vacationing time (first two weeks of June) strictly for educational purposes and now planning to work hard for the whole summer and take some time off on weekends only.
