This is my simple and real every day carry. Most people can't or won't carry a big kit everywhere they go. I know I won't religiously carry a kit everywhere, when I will never have a need for half of it. So here is an Intractable on what I carry on my person at all times and why I carry it.
Step 1: Low Tech Items
A Sharpie and Chapstick.
For writing I've got a sharpie its pretty effective for writing on any surface. I often need to write down a shopping list, dimensions, assignments. Note that I don't carry paper if I write something down I'll likely loose the paper. Therefore I tend to write on my arm. If I lose my arm I have bigger things to worry about than whatever I had written on my arm.
Chapstick for my frequently chapped lips. I have a very attractive girlfriend whom I enjoy kissing so soft lips is important.F
