Day 7 - How can the GM make the stakes more important?
This is an interesting question, but in many ways it's too generic.
That said... One of the best ways to make the stakes more important is to make the adventure and whatever the central plot is personal to the player characters. This plot could be personal to the individual player character, and thus drawing the other characters in with him or her, or it could be personal to the group as a whole, though that can be difficult to handle and set up at times. Another way to make the stakes important is to set a time limit on how long the player characters have to accomplish the goal of the mission/scenario. By and large, I think making the players invested in the situation and the goal of the adventure is the way to handle this best.
