I disagree. I've had an Adderall prescription for almost three years now, ever since my second semester in college. I don't take it 7 days a week, usually 3-4 times a week just so I can pay attention in lectures and to efficiently finish papers and study. It will effect everyone differently but for me It will last about 5 hours and during that time I can pretty much nonstop focus on what I need to pay attention to whether it be a lecture, homework, or studying.
I don't take it during any of my breaks(summer/spring/winter). Side effects are minor at the dose I take which is 20mg 3-4 times a week. Max once a day. Maybe a slight headache/nausea after it wears off, sometimes no side effects.
Before my prescription I was able to get through highschool fine but in college its harder to bs your way through classes, especially if your majoring in STEM. There is a balance between willpower and talent/interest you need to succeed in school. If your researching a subject you are interested in you will find it easier to focus on it. I found that no trick was able to make me focus on shit I didn't enjoy. (doing school work in library, turning off phone, no social media, anti-procrastinator apps). I would rather stare at the wall than study for a compsci midterm.
It will be different for everyone. For some people they will be able to find a way to end their procrastination habit and succeed in school or whatever. For me I wanted a solution. My first semester I failed two classes and was in academic probation. The following semester I found a psychiatrist and got an adderall prescription. Ever since then my classes have gone great. Mostly As and Bs with the occasional C. I know multiple people who got through college w/ an adderall/similar drug prescription and now work full time still using adderall, their bosses knowing they use it, w/ no problem.
WARNING I would not get an adderall prescription if you have an addictive personality. It is very similar to meth and if you abuse it it could ruin yr life. DO NOT tell anyone you have adderall. They will ask your for some and never shut up. If you do give them some they will probably ask again. Plus its very illegal to share yr prescription for a controlled substance. Final thing add/adhd is a real thing no matter what some people will say. Sure many people will claim they have add/adhd as an excuse but its still real condition. Chemical imbalance in brain. If you have add/adhd you will still be able to focus on the things that you find mentally stimulating. Drugs not only solution.
