Does being a deeper thinker mean you are a hard worker?

Last week i read two different articles. One was called "How to Become a Deep Thinker at College” and the other one was called “Work Hard or Work Smart”. Together both of these articles give me the idea that in order to be a successful college student you must be able to be a critical thinker which means thinking beyond outside and beyond the normal, as well as being able to be a hard worker. According to the "How to Become a Deep Thinker at College" article , it says that in order to become a better thinker you must double your school work schedule which means that you won't have a lot of time for activities to go on. I disagree with that statement because i think in order to become a well-rounded deep thinking college student is to be able to join different activities and clubs so that you can learn from them and see where other people are coming from. You can't always get all of your skills from a book. I can understand where the author is coming from but according to things that I’ve heard from professors, a college student should be involved with their campus community. Not meaning that a student should overwhelm themselves by joining too many clubs but just as much as they feel would fit into their schedule. The other article “Work Hard or Work Smart”, had great points where it said in order to work hard you must be able to plan things out and making sure that you stick to your plan. Like planning out when you are going to do your homework and for how long for each subject. I like this idea because; I have been using this since I was in my junior year of high school when I started working. It helps because not only do you have a set plan but it also makes sure that everything will be done at a certain time and that you won’t ever fall behind in your work. I would like to know that if this idea worked for everyone and if it does , what benefits do they get out of it?
