Actually go and do the activities you want to be able to do, in a safe environment.
Camp in your garden. Walk for miles through town. You'll soon find that things which get hardly any attention on survival sites really matter.
Try walking in your office shoes, sleeping without a sleeping bag, having a frameless sac. It's awful!
Just reading about it isn't enough.
Then when you do get the right gear and know enough; you'll discover how wonderful it is.
I'm just back from working in arabia and now keep inventing reasons to go down town, or to the local shops just to see the trees and grass.
They are terrific morale lifters and provide a regenerating environment. I've never come back from a walk in nature, in a bad mood, no matter what state I went out in.
