Networked problem-solving?

I've been thinking around an idea for the past couple of days and need a sounding board, so here goes.
When you consider your problems, or those of your loved ones, do they ever strike you as in some way connected, or interconnected?
Ok, so here are some examples I can think of...
A heavy gambler could also be a heavy drinker, and could also have relationship problems.
Or, Someone suffering from obesity could also be suffering from money problems.
Or, someone who is "stuck in a rut" at work might might also be "stuck in a rut" at home.
So, when it comes to tackling problems how about doing a kind of mapping illustration on paper, or just in your own mind, of the ways in which the problems are connected?
Then how about making a decision in your own mind to "work on one of them this week" or something like that, with the certain knowledge that in helping to resolve this you will also help to resolve the problems/issues/behaviours that are interconnected with it...
So I suppose I am angling here at a kind of "networked problem-solving"...
The advantage of this approach to problem solving is that you can start small, really, really small...And have the full knowledge that if you resolve the small-scale issue, the large scale issues which are connected to it (in your mind-map) are also likely to be on the road to being sorted out.

Example:
Let's say you procrastinate on something like unpacking your shopping when you come in from the supermarket...Ok, find a way to get on with that one straight away...And get in to the habit of unpacking your shopping first thing, just as soon as you come in the door. Get that new habit figured out and scheduled in...Then maybe, just maybe, you will see that having resolved that procrastination behaviour you will notice that other behaviours on a large scale, over which you have endless procrastrinated in the past might just melt away.

If the problems can be networked then, well, so can the solutions?
