It's all about starting as early as possible and diversifying.
Savings, HSA, IRA, mattress money, Gold, Silver, Bullets/guns, food & water, bonds, High Risk/yield investments and low risk/yield investments.
I see all of the above as absolutely necessary. Even if I only contribute a few bucks to each every month, it adds up in the long term.
I'm young enough and not averse to risk, so I buy the dip whenever I can. Has worked well so far.
I keep enough food and water for 6 months for every member of my household, including pets. I rotate it in and out. I started small and just kept building.
A lot of people think that is crazy or unnecessary, but honestly if we see massive inflation or a disruption of the food or water supply, it will literally save my family. It's easy and required minimal investment over a long period of time to build up.
HSA is huge. I used to not have insurance at all and instead invested in HSA accounts- used very little over the years as I stay away from hospitals and clinics unless absolutely necessary. I'm healthy, but as I've gotten older, grown my family (And the .gov requires it now) I have lots of insurance- health, accident, life, etc.
Any company I've worked for that matched- I invested into IRA's, always contributed at least double what they would match.
I invested into gold when it was around $300.00 an ounce in my youth and continued to buy a bit here and there when it was at good prices. Same thing with silver and palladium. I've even gone copper dumpster diving (With permission) at commercial construction sites before they realized how much $$$ they were tossing when copper went up and started salvaging it.
I have never amortized anything other than a home/property purchase. Save up and buy it, or don't buy it at all. Unless it is a real emergency that is.
Budget. How many folks just don't do it? MOST!
With alittle planning and forethought as well as some sacrifice, you can provide for your future in a big way.
