To get this achievement, you need to start a new game so you can go back to the first mission. You start off in Megan Reed's office. Don't leave like Megan is urging you to do. There are 6 items in total, here is a list.
The Ebook on the sofa to your immediate left.
A toy car on top of a filing unit in between a stack of papers and a printer (immediate right from where you start off).
A book on Megan's desk that reads "Being More Effective", it's about 3 feet to the left of the toy car.
Next is the e-mails on Megan's computer, you must scroll down each of them for it to count towards the achievement/trophy.
The picture is to the immediate left of the computer.
Lastly, the newspaper is at the end of the desk (on the left side).
