I believe most people have some kind of plan when they head for an outing in the mountains. At a minimum, at least we check to see if we have a few essentials in our packs. Sometimes I just get a few things together and get my kids in the car, then drive to a trailhead for a day-hike. But for the longer and more challenging trips I do a lot of planning. What date to go, how to get permits, how to coordinate time away from work and family, what partners will be available, what to wear, what to pack, where to camp, what route to take, what equipment to bring, how to shuttle vehicles if neccessary, what are the options if an obstacle is encountered. And the planning goes on from there.
In order to make a plan first you have to have some kind of objective (O.K. call it a GOAL) in mind. I have a lot of goals. Not just mountaineering but life goals in general. I have'nt paid any proffessional, lecturing snake-oil salesman to tell me how to set my goals or plan the steps of how to acheive my goals. Some of us have to set our sights on something to motivate us to take action.
Yes, at some point you have to execute your plan and just "git-er-done".
I just got back from a six-day trip where I along with two partners summited Polemonium, North Palisade, and Starlight Peak. I made a goal several years ago to climb all 15 of the California Fourteeners. The three peaks we climbed on this trip were a part of my overall goal. I along with my partners, spent months discussing details and planning. I derived great satisfaction from the planning phase of the trip but the real reward was getting out there and doing it.
In my opinion, goals and planning are important prerequistes to execution. I acknowledge there are some people who are more talk than action. But I wouldn't suggest to those new to mountaineering to head off into the hills without a plan.
