How will I communicate these connotations? (referring back to The Student Magazine)

• Hard-working - A way that one of the magazines I analysed did this was by making the cover photo a picture of a boy doing work. To the side of him, he has a board, with equations and scribbles on them. For all we know, he could have been doing something else entirely, but we trust the magazine that they're showing us a hard-working student, as opposed to a lazy one. This could, of course, be an option. Another option is to have lots of cover lines showing for more educational side of the magazine, rather then the most interesting articles and the ones my target market would like to read. I think I'm going to go with the first choice rather then the latter, because I have reason to believe that it would sell better with those in my target market. 
• Fun, energetic, lively - The first magazine I analysed had a lot of interesting articles, highlighting television, gaming, gadgets, fashion and music, showing that some students will be interested in other things besides studying and school, that they like to have fun as well. The lively could easily be achieved with right colour choices and bright colours with the images (example, the white text over the  green grass. White text stands out more on any colour)
• Simple, easy, tidy - As you can see, each headline is laid out clearly and easily, the interesting articles at the centre of the page (revision tricks uncovered, all caps!), the other main articles to the left of the page (television and gaming, oddly) and articles that not everyone may be into at the bottom of the page (gadgets, fashion and music) Each tag for the article block are in a different colour, sectioning it off well, and let us know what we want to look at.
