That everything I buy can be measured as totalCost/wages*0.82=hoursCost.
I love measuring things in hours.
Let's assume I make 12/hr. Is 24 cans of soda really worth more (taxes) than an hour of work? 12 bucks might not sound too bad, but over an hours wages does.
I used to have to focus my attention on at least two things. Like 80/20 or I couldn't focus. That 20% would be enough to keep my mind from wandering from the 80%
But, whatever works for you.
Personally, I think going without always on access to the web would do be wonders.
