I'm a lifelong advocate of living within 60% of your means. In other words, if you make $1000 a month, you should save $400 and live on $600. You can actually do this if you're willing. It's simply a matter of discipline.
I started work at 14 and followed this rule. So, when I was 20 and decided to go overseas to find work and adventure, I had enough savings to afford to go. When I was 30 I had enough savings to open a store in the newly extended Las Vegas Hilton. Etc. To me, reserves are the key to opportunity. Many dreamers come to me with grandiose business plans and if they just had the money......but of course, they don't because they have debt instead.
Now I'm 69 and "retired". For the last decade, I've spent MORE than I've earned because I help out certain family members. I can do this because of my savings. I'm now going deeper into the landlord business, I just won my bid for my 7th rental unit. I intend to end up with 10 rental units and I will pay cash for them, because of my savings.
My parents were depression era people and never spent money on anything. I'm not quit as frugal as they were but in principle, I followed their neurotic fears by saving money and never using credit. I've only bought one house on credit when I moved from Korea to Las Vegas. I wanted to conserve my cash for my new business. After that, I always paid cash and lived in inexpensive homes.
I use my credit card for EVERYTHING and it is automatically paid in full each month. I use the points to buy books on Amazon, my one compulsion, because I read authors too obscure to be found at the library.
I've never met anyone with the same philosophy as myself. Nobody wants to live below their means because the NEED McMansions and Beemers. Fortunately, I don't.
