Very broad subject.  Start with small steps.  Try out your gear overnight in your back yard or a car camping environment first.  You will probably make adjustments.  Then do an overnight  to an easy destination.

A week long trip requires careful planning to assure adequate, but not excessive, food and fuel.

The whole idea is to carry adequate gear for the conditions you encounter and keep the weight of your load within acceptable limits.  This is always a challenge.
