You might notice that all the answers so far seem quite similar and they rarely emphasize any skill you'd associate with camping.

Most of them emphasize staying alert to your entire situation, such as always knowing where you are, whether you are thirsty and where you'll find water, where your route takes you next, what is the weather doing, and so on. I agree.

It all boils down to anticipating problems before they arise and taking early steps to ensure they stay small and easy to deal with. The more unfamiliar the setting and situation, the more caution you need to apply and the more you will need to learn as you go.

Bring that atitude to everything you do on the trail and you will learn quickly and be successful, because each experience you have will lay the foundation for future mastery and wisdom.
