&gt; Just curious, are there any anti-mustachians who 1) bust ass to maximize earnings, 2) have unabated spending habits, 3) believe they are happier to live such a lifestyle?<p>I&#x27;d classify myself as a bit of an anti-mustachian in the sense that I pay 0 attention to 99% of purchases. I don&#x27;t think twice about going out to dinner regularly, buying a round of drinks, or going on random trips. It&#x27;s rare for me to look at a receipt.<p>Despite spending freely, I still manage to save around $80-100k annually.<p>Increasing earnings is far more effective than trying to minimize earnings. Trying to cut your spending by 25% is pretty challenging, but making 25% more is totally doable and often involves just getting a few competitive job offers. As Ramit Sethi sometimes says, skipping lattes never actually lets someone retire early.<p>A lot of the things MMM recommends are actually economically irrational for developers (unless you enjoy them). Why would I ever cook when I can earn $150 from the equivalent time and get a nice meal delivered for $20?<p>The only bit of spending I pay attention to is rent, because that can eat up a huge portion of your salary if left unchecked—particularly in the places with the highest salaries.
