[ad_1] — First some great news: because of your support in reading and sharing this blog, it has been able to earn quite a lot of income and give away over $300,000 so far. The latest $100k of that happens at the end of this article. Please check it out if you want to feel good, learn more, and even join me in helping out the world a bit. — As I type this, there are only a few days left in the 2010s, and holy shit what a decade it has been. Ten years ago, a 35 year old MMM and the former Mrs. MM were four years into retirement, but not feeling very retired yet. We stumbled out of 2009 with a precious but very high strung three-year-old, a house building business that was way more stressful than it should have been, and a much more rudimentary set of life skills. It was a time of great promise, but a lot of this promise was yet to be claimed. Ten years later, despite the fact that I have one less marriage, one less surviving parent, and ten years less remaining youth, I am in an even better place in life right now, and would never want to trade places with the 2009 version of me. And on that measure alone, I can tell it has been a successful decade. This is a great sign and it bodes well for early retirees everywhere. Compared to the start of the decade, I am healthier and stronger physically, wealthier financially, and (hopefully) at least a bit wiser emotionally. I’ve been through so much, learned so much in so many new interesting fields, and packed so much living into these 3653 days. A big part of that just flowed from the act of retiring from my career in 2005, which freed me up to do so many other things, including starting this blog. It has not always been easy, in fact the hard times of this decade have been some of the hardest of my life. But by coming through it all I have learned that super difficult experiences only serve to enrich your life even more, by widening your range of feelings and allowing you to savor the normal moments and the great ones even more. Ten Years of Learning in Three Points I think the real meaning of “Wisdom” is just “I’ve seen a lot of shit go down in my lifetime and over time you start to notice everything just boils down to a few principles.” The books all say it, and the wise older people in real life all say it too. And for me, it’s probably the following few things that stand out the most: 1) This Too Shall Pass: nothing is as big a deal as you think it is at the time. Angry or sad emotions from life traumas will fade remarkably quickly, but so will the positive surprises from one-time life upgrades through the sometimes-bummer magic of Hedonic Adaptation. What’s left is just you – no matter where you go, there you are. 2) But You Are Really Just a Bundle of Habits: most of your day (and therefore your life) is comprised of repeating the same set of behaviors over and over. The way you get up, the things you focus your mind on. Your job. The way you interact with other people. The way you eat and exercise. Unless you give all of this a lot of mindful attention and work to tweak it, it stays the same, which means your life barely changes, which means your level of happiness barely changes. 3) Change Your Habits, Change your Life: Because of all this, the easiest and best way to have a happier and more satisfying life is to figure out what ingredients go into a good day, and start adding those things while subtracting the things that create bad days. For me (and quite possibly you, whether you realize it or not), the good things include positive social interactions, helping people, outdoor physical activity, creative expression and problem solving, and just good old-fashioned hard work. The bad things mostly revolve around stress due to over-scheduling one’s life, emotional negativity and interpersonal conflict – all things I am especially sensitive to. So while I can’t control everything, I have found that the more I work to design those happiness creators into my life and step away from things that consistently cause bad days, the happier and richer life can become. Speaking of Richer: I recently read two very different books, which still ended up pointing me in the same direction: This Could Be Our Future, by former Kickstarter cofounder and CEO Yancey Strickler, is a concise manifesto that makes a great case for running our lives, businesses, and even giant corporations, according to a much more generous and person-centric set of rules. Instead of the narrow minded perspective of “Profit Maximization” that drives so many of the world’s shittier companies and gives capitalism a bad reputation, he points out that even small changes in the attitude of company (and world) leaders, can lead to huge changes in the way our economy runs. The end result is more total wealth and happier lives for all of us – like Mustachianism itself, it really is a win/win proposition rather than any form of compromise or tradeoff. In fact, Strickler specifically mentions you and me in this book, using the FIRE movement as an example of a group of people who have adopted different values in order to lead better lives. Die with Zero*, by former hedge fund manager and thrill seeking poker champion Bill Perkins sounds like a completely different book on the surface: Perkins’ point is that many people work too long and defer too much gratification for far too long in their lives. Instead, he encourages you to map out your life decade by decade and make sure that you maximize your
