I tend to think in terms of the 80/20 rule: 80% of your desired outcomes come from 20% of your efforts.. 80% of the value you get comes from 20% of your spending, etc. (The exact numbers are not that important but the idea is that the majority of the value you get comes from a minority of your efforts or inputs. Of course, what minority that actually contributes to most of your results may not always be obvious.)
When it comes to saving money, I tend to focus most on keeping my large expenses down.. Housing and Cars are the main areas. I try to minimize my monthly expenses (mortgage, insurance, internet and phone bills, etc.) while maintaining an acceptable standard of living. However, a lot of times, I could care less if I missed a $0.50 coupon for oranges in the papers or got gas from a gas station charging $0.10/gallon higher than the cheapest gas station in the area. If I was craving oranges and a $0.50 coupon for them fell into my hands from the sky, I would still of course use it but I won't spend a ton of time searching for it.
Is this a dangerous mindset? I tend to put a ton of effort into getting the most value out of the big ticket items but these small expenses do not receive a fair share of attention. Sure, the small expenses could add up if I don't pay attention to them but there's an opportunity cost to that attention. The same effort could have been spent further optimizing my larger expenses or figuring a way to earn more money (side job/business, career development, etc.) Is my way of thinking dangerous or still in line with the Mustachian philosophy?

(I'm a Macrofrugal type by heart.)
My dad always said "Your mom knows how to save $1, but doesn't know how much easier it is to make $10."
Now, this can't be taken at face value, but I learned what he meant was that Mom tended to focus on cutting expenses and being frugal on the
spending part of the equation, while not being too savvy on the
income part.
At the end of the day Savings = Income - Expenses, so $1 saved is the same as $1 earned (more like $1.25 earned, but same idea ignoring taxes).
You can't get rich by cutting expenses. If you spend $30k/yr, you have a maximum addition to savings of $30k. However, the Income side of the equation is unlimited, relatively speaking.
If you enjoy cutting coupons, and saving $.50 here and there, then by all means go for it. At the end of the day, this is a good way to live as it means you are always thinking about getting the most "bang" for your buck.
I agree it is possible to
improve your situation through saving, but for long-term wealth and true FI, you need to work on your Income factor. I personally am frugal in the sense that I like to buy nice things on sale. Calvin Klein tie on sale for $40? No way. Calvin Klein tie on sale for $20? Yes, please!
I don't cut coupons, or scan the papers much at all. I buy all my groceries at Trader Joe's and honestly don't really look at the prices (as long as the total ends up between $300-400/mo and I don't throw much away, I'm satisfied). I buy nice clothes, but only when they're on sale online (I rarely go to actual stores to just look around). Brooks Brothers shirt for $90? No thanks. Brooks Brothers shirt for $50? Yes, please!
Personally, I don't want to retire early and be a rich troll living under a bridge (for lack of a better metaphor). I hope to be wealthy, have nice things, do fun things with people I care about, and give back in some way.
I think the best way to make sure you're on track is to set an overall goal (e.g. save 40% of net income), and then find out a way to reach it.
There are a handful of ways to save money, but a million ways to make money.
