Sooo, I'm not a financial expert by any means of the word, buuttt this is my favorite financial topic of all time.
Currently, 2/3rds of my paychecks are going towards my home's down payment. Saving up for land takes some serious effort. If it weren't for that, I could easily already drop down to working part time and chill out for.. like.. eternity.. But one thing at a time.
I don't have financial debt, I have a good credit score, shove a few bucks into savings and investing occasionally, etc. etc.
I did this many different ways.. One of the biggest things I did was serve my country, which gave me free education, free health care for life, and a resume that will build on anything I do. I also went to school without working full time (besides when I very first started) and saved money doing stereotypical stuff: eating at home, living with parents and paying rent vs by myself, etc. etc. I know there are many people that cannot serve, but there are many things I could not do either--like live without a car since I was in the deep south. Pretty much impossible to get anywhere without a car.
I held down a lot of different jobs, and I was not afraid of taking on anything from hard labor unloading trucks and using a forklift to kid-friendly yoga-mom-inspired yogurt shops. I did anything and everything as long as it paid and gave me the flexibility I needed at the time.
I also saved money where ever I could. I still spent money on the things that mattered to me at the time--I don't find the video games I ever bought a waste because at the time they gave me joy, and relaxation, and they also kept me from going out and spending money at shops, restaurants, bars, etc. When you're grinding for bosses it's easier to say "Yeah, just eat this sandwich at home" vs going out to eat. But... I for my clothes for free or less than $3 a piece. Mostly for free. I wear things until they're dead and done. I'm not very fashionable as you can imagine. (This has changed since I moved to NC where fashionable people get rid of shit constantly). I don't spend money on a lot of vices people have: Make up, new gadgets, alcohol, fancy/organic food, music concerts, non-free events, smoking or e-cigs, coffee/caffeine in general, etc. I don't spend money on anything like that... No monsters, no star bucks, no nothing. I just don't do it.
I take care of my health and exercise.. I do preventative maintenance on my teeth and go to the dentist and actually listen to them, I floss twice a day without fail, I do universal precautions for healthcare (washing hands, cotton underwear, sanitation precautions for food preparation, etc.) to keep my health in order. I work out and generally stick to something active most days of the week. This isn't hard-and-fast, but it is general stuff that research has shown to help people save money, time, and be happier.
... I think the biggest thing though is that I take pleasure in saving my money. I genuinely enjoy not dissolving my money straight away--but rather having an allocation that feels right when it goes into that slot. While I've become more relaxed since getting my first decent paying job in my life and generally speaking I am less frugal than I ever have been... I still think I am far more frugal than the average person I come across, and certainly more so than the people getting my same pay rate. Generally speaking, it is because of this principle.. I don't enjoy money disappearing. I like knowing where it goes and when it is going there.
I can write more specific things if people want them, though I've sprinkled these things throughout the forum. I like the Moustachian principles as they can apply to one's own life--obviously I have a car and I use that car daily, but that's suitable for where I live. You need your own brand a frugal. People who live pay check to pay check know how shitty it is and feels. And... Really.. I'd give up anything to never do that again. And I do.
