The social aspect of work is a good one on monday; while you're catching up, you're also generating better morale all around. Think baby steps on tuesday and wednesday: if you're holding your breath for big progress or fresh projects, you may turn rather blue. Make the end of the week all about relationship building. You can turn a random contact into an invaluable link in your network with a little tactful digging about what the two of you can do for each other. Your tact also comes into play if you're working this weekend, when you can smooth over a difficult situation.
