Don't worry about everything. If you do you will get pulled in too many directions and it'll be hard to focus on the things that really count. Instead of worrying about everything survival related, worry about these five SHTF items you should keep on you!

Paracord bracelet
I sometimes wear the paracord bracelet my old private investigations partner made for me just to have some kind of cordage. It certainly comes in handy to have something on occasion but you kind of need more than what’s easily carried or worn to really do anything with it.

List of important information
You can’t always rely on getting into your cell phone to get phone numbers or addresses. What I’d suggest is that you make a list of the phone numbers of anyone you might have to contact in an emergency if you had to use someone else’s phone, along with any other information you think you might need that you’d usually have to get off your phone or the internet.

A pen
In a survival situation, they can be used to leave notes for rescuers or to write notes to yourself about the locations of water sources or other things you may want to come back to later while you’re stuck out either waiting for rescue or trying to get out.

A lighter
My go-to way to start a campfire is just a cheap-ass Bic lighter. It works in most situations and will fit in your pocket quite easily. You may be tempted to get a Zippo because they’re cooler, but they won’t hold fuel as long (although smoking-type chicks dig them on dudes better). In any case, just make sure you have some kind of lighter.

A good knife
One of the most useful items you can carry is a good knife. You may not ever find yourself in an actual survival situation but if you had a knife with you that could work for that in a pinch, that’s one less worry you’ll carry around in your pretty little head. I personally carry a Gerber 06 tactical with s30v steel when I’m wearing jeans and can fit it. Why? The s30v steel is much better than most of the crap out there and still not crazy expensive.

Most of these can be included in pockets or belt loops. Some might not get you through security, but for the most part, you will be relieved when SHTF and you're covered with the basics. For more items, you should carry on a regular basis, visit Graywolf Survival!
