Enjoyed reading most all of your inputs on this topic. As the ultimate cheapskate, I had a few more to add.
To me , saving money is like a game that you can enjoy getting good at, and turn a profit doing it.
First, with you tube instructions available today, many jobs can be performed by yourself rather than hiring someone who often has less interest in the outcome than they should have in doing a job well done. For instance, we wanted new tile in our home this year. Two different installers told us they charge between $12 and $15 / sq ft labor to do a tile install. So, wife and I decided to do it ourselves. It is a cheap date that pays. DO NOT FORGET THE TAX SAVINGS IN PERFORMING YOUR OWN WORK.
tile job- 500 sq ft @ $10/ sq ft = $5,000. To have $5,000 to pay out you must earn at least $7,500 in most cases due to taxes incurred.
I recall reading a book many years ago that suggested one cost savings and wealth building trick was to perform as many tasks yourself as possible, thus "hiding" the labor from taxation . Example- instead of working two days for paid wages which get taxed, I work two days on a project that saves me $1,000 in labor i would have paid out for said service, such as painting my house. The house goes up in value from the restorative process of painting, but I do not get taxed on the labor spent to enhance its value. If I had bired the job done for $1,000, i would have had to earn $1,500 to have $1,000 left over after earnings taxes are deducted.
I track all of my hidden value savings in a year to see how much value I earn in hidden wages.
Brings me to my next point, live as frugal as you can. My wife is a professional employee, so all of her earnings are exposed to taxes. Fortunately, we can live just off of her income as we spend very little on anything outside the home. Eat out 3-4 times per year, drive old cars etc. We take walks , do staycations, fix our own food, garden (not really a money saver, more just a simple pleasure),
More than anything I think saving money is a mindset. Some people could care less about saving (a couple of my kids feel this way ) , while others make it a game and practice and hone their skills for a lifetime.
Is it really saving money? I bought a five gallon bucket at Lowes for $9 and one at Menards for $3 to do the mixing of our tile mortar. The Lowe's bucket is much heavier, but it takes 15 minutes to thoroughly clean after filling with mortar so I can reuse it the next time. The $3 Menards bucket works fine, but will not hold up to continual service. After cleaning buckets for 5 times or so, I decided the best savings was $3 bucket at Menards then throw out instead of clean. Cleaning made for a savings of approx $18/hr ( $3 x 4=$12 plus money needed to earn to purchase bucket exposed to tax =$18). I can far surpass $18/ hr on most jobs I do so it makes more since to save time than money in this case.
