Super simple achievement that can be received within minutes after starting the game.
Once you’re looking out the window at the beginning of the game, exit the room. Go away from the camera and down the hallway before making a left into the room with the open door. Go near the left side of the room where the cabinet is and after your character speaks you can interact with the wall. Move your cursor now to a little jewelry box on top of the cabinet and open it. Nothing will be inside and the game will now let you use Insight by holding down LB. Soon after you can use it when inspecting items and even just walking around in certain areas. Just keep holding down the LB (I tied a rubber band around my controller) until the 15 minutes pass and the achievement will pop.
