The work is piling up

Admittedly, part of it is procrastination. I don't feel like I'm avoiding the work, though. It's more that I don't know where to start. The work is piling up because I'm beginning to see what I need to do, and how I need to do it. This rings true on all fronts (home, work, school). There's so much that I want to do...

I think my problem is that I’m looking at it all from the top down instead of just working through it on a more micro scale, handling tasks one at a time.
