Do you practice a "belt and suspenders" approach?

Really, I have always been a “leap naked into the void” type except for two things: when others are involved (if I am making travel plans for us all) and for power outages (having lived for many years in a place where power was iffy).
I am old enough to have never started relying on electronics for daily tasks, so the alarm, appointment, and list features of my devices go unused. I still wear a watch.

Just a belt, I guess.

HAHA, GA GA! I’m pretty competitive and ocd, so yes, of course I over prepare not only for my personal preferences, but also to ‘win’.

Sealing an envelope then taping it shut (in case of defective glue? I don’t know.)
Certified mail if it’s legal or important. (making sure it gets there)
Tracking numbers for every purchase, and I literally track it. (my stuff, my money)
Calendar at work and at home, paper. (so I’m never late or miss appts)
I keep bottled water and long-term staples in the pantry in case of apocalypse (haha!)
Always buy the huge bag of dog food for my ‘kids’, same with bird food.
Buy the family size tissue.

*I’m so weird, but I think it helps me psychologically due to a childhood of running out of things and being out of control -due to the alcohol abuse. I just like to control my world, when I can. Sometimes I’ll let things run out just to push myself out of my comfort zone, and I get a mental itch until it’s completed.

I keep a wind up torch and radio in my flat and a supply of candles. I sometimes email important files to myself so I can access them anywhere from any device. When hillwalking I bring a paper map and a Silva compass as well as the digital map on my mobile phone. I have looked at buying a rope ladder as a way of escaping my flat in the event of fire but I haven’t seen anything suitable yet.

I have flashlights and candles, but the candles are simply the ones around for formal dining. At heart I’m a seat-of-the-pants type fella. I’ve improved considerably with age, but actually I’ve had the luxury of the wife who is the queen of redundancy. She renewed the overpriced deluxe AAA card for at least 30 years, and I used it out of spite just last month to allow someone else to wrestle with a flat tire on the van.

Sometimes I do, sometimes not. In theory I’d like to for the important things, but more often than not, don’t.

(You just reminded me to back up my data… thanks.)

What you’re talking about is living defensively. And, yes, I do. I don’t go whole-hog but I try to keep my bases covered as much as I think needed.
I have a Coleman camp stove that I converted to propane. I keep propane cylinders for it and when the power goes out, like it often does here, I can make tea and/or breakfast. I keep a good supply of 20GA. and ..22 rounds for my firearms. I keep some BBs and pellets so I can shoot squirrels for food, and fishing equipment. I have oil lamps with plenty of wicks and fuel. I keep several gallons of drinking water handy. And matches.

I use “reminders” on my phone, while at the same time, setting an alert on my phone, marking the event on my paper calendar in my room, marking the event on a white board in the kitchen, and putting a post it note on the front seat of my car.

I have a lot of different types of activities going on in every different week. All the notifications helps me not to double book.

Some interesting answers here so far. Thank you.

@kritiper, I think that’s what you’re talking about. I’m not. I’m talking specifically about redundancy. My details include the statement: I’m not asking about storing or stockpiling resources.

I had a friend tell me once that you never trust a guy that wears a belt and suspenders at the same time. They’re usually out to take your money. But that is the apparel choice, not the planning/preparation effort. I generally am a one and done kinda guy when it comes to planning. For appointments I write it on the calendar or set a reminder, but never both.

@Jeruba But you are talking about being prepared for unseen, unexpected, possible circumstances.

A person who wears both a belt and suspenders isn’t wearing multiple pairs of each, he or she is just making certain his or her pants don’t fall down.
