Decluttering

What do you do if the clutter in your life is a direct result of the fact that your day job makes it difficult to focus on your passions due to the time it takes away from your actual life?  How do you declutter a paycheck?

Clearly, by making that paycheck less and less important, but the issue I'm running into is the fact that everything else I want to do also takes time, and when the day job takes up nearly 12 hours of my day, it's very difficult to accomplish much of anything else during the week.
