My motivation in the beginning was "coaching" from my previous husband to climb Poko with him, then he started the "coaching" to Marcy. I never even liked the woods and surely didn't want to hike in them. Then he started naming other High Peaks for us to climb. I didn't even know what a High Peak was. After climbing several of them, it became more of a sport to me, exercise, getting away from the house, work, stress release time, seeing beauty, the Mountaintops, etc. Then the challenges began, the self esteem, self confidence. Climbing helped with all of that. It was a way to prove that I could do something "worthy," of myself. Prove to others, who didn't believe, that I could do it, that I could.
I too, didn't know about the Forty Sixers or the patch then, so it surely wasn't for that reason.
As time went on the Mountains became more, adding Spiritual Meanings for me as well. Peace and relaxation. There were lasting friendships to be made, that were meaningful. Others that enjoyed the same interests, becoming acquaintances. Helping others with their goals. The Mountains were my home, away from home. They were my friends and a deep love for them. Climbing just became so much for me. I feel all of those same feelings and more, no matter which mountain or trail I am on. I don't need lists or goals to keep me climbing, because all of the other rewards received are so much more meaningful for me.
