I stumbled on this forum about 2 years ago while researching Roth versus Traditional investing - I think that I may have have found a link from the Mad Fientist. Over this time, here are the main things that I have stuck with me:
Spend money on things that REALLY matter - Sell things that don't matter. This is a biggie for me! I had enjoyed boating for many years, but began to realize that although I still enjoyed being on the water, between our short summer season, and other family activities, I had a huge sum of cash depreciating in my garage between the boat and the truck that I used to tow it - just so I could go on the water maybe 5 times a year. This stuff was also costing me in insurance, registration, maintenance, repairs, winterization, and storage space. After the facepunch I received from this forum, I sold both which netted me $43k in my investment account, stopped the annual leak of $5k, plus left a really nice open garage in which all of our cars now easily fit! I fully understood why they say that the second best day of boat ownership is the day you sell it!
Keep a positive attitude at all times. I used to think that the people who said this were just serving Kool-Aid, but I have noticed that I am in such a better mood when always looking on the bright side, and I find that I surround myself with folks with similar attitudes. I now find myself internally laughing at people who are all bent out of shape at something fed to them on Fox News. Shut that crap off, and go outside and enjoy a walk with your dog!
Contentment. Be happy with what you have, and don't measure your success against what the Jones's have on credit. My wife and I have been fairly good with money most of our lives, to the point where we have absolutely no debt, and a significant amount of FU money. We have stayed in our first home, and we generally keep our vehicles for many years. The key is to take care of your things, and keep up with maintenance. No one who sees our 10 year old TSX thinks it is that old, not to mention that is has over 200k miles on it. That said, the plan for this car iis for it to become our daughter's first car, then buy a replacement for my wife.
Listen to advice, but think for yourself. I am not nearly as extreme as MMM, for example, as I will never be without a car. However, I have taken the other 70% of his advice and applied portions of it to my life where I hadn't been using it already. For me, this applies with Dave Ramsey also. I was never in debt, but I find a lot of his stuff very inspiring once I sift out his right wing and religion rants. Once you cut those out, much of his message is very similar, but with 'Gol Dang' instead of the real swear like on MMM! A prime example of thinking for yourself relates back to the Roth versus Traditional arguement, which I how I got here in the first place. Most of the general public (including Dave Ramsey) automatically defaults to saving into a Roth today, because 'tax rates are only going to go up'. But my issue was that every dollar I could put into a Roth would be taxed at the 25% tax bracket, and not at the 7-8% effective rate. However, between this forum, ERE, and Mad Fientist, I was able to determine that a traditional was indeed a better solution for ME, instead of blindly following the Roth herd.
Well, that's all I have for now. What has stuck with you?
