That about covers it except for; pay cash, separate want from need.
I pay by cash back credit card which I have set to pay in full every month. Its not huge but conservatively, I save between $500 and $1000 per year that way.
I also only get YouTube TV for 4 months a year during college football season. You don't need cable TV the rest of the year. Between Youtube/Rumble and what I download from torrents sites, you are spoiled for choice as is.
I not only don't get take out. I very rarely eat at restaurants at all. I like to cook. Its healthier anyway.
I switched my data plan for my phone from AT&T ($82 per month) to Charter ($27 per month) for the same unlimited plan. I have never noticed the slightest difference in quality. The $55 in savings per month is nice.
That I've listed above is a savings of at least a few thousand per year. Not earth shattering, but its nice and it doesn't lower my standard of living in any way.
Except I use my American Express card to buy all purchases that take that card. Which I pay off every month.
In exchange AMX gives me 6% back on grocery store and pharmacy purchases.
3% back on gasoline/diesel. 1% on every other purchase,
I get paid back in cash or a credit to my balance.
