How to persuade my girlfriend to climb the mountain!

In communication and persuasion, we should consider win-win factors.

Your problem now is that you want to climb mountains, but your girlfriend doesn't want to climb mountains, right?

Then you should consider that those things are beneficial and attractive to her! Then minimize the fear of climbing mountains.

For example, she is afraid of being tired and doesn't like sports, but she likes shopping.

Then you can tell her that climbing mountains can lose weight first, so she doesn't have to be afraid of gaining weight. If she is afraid of being tired, she can climb Mount XX first. Mount XX is relatively short, so she can climb slowly with her. It's closer to the commercial street in XX after going down the mountain, so you can accompany her shopping.

This kind of communication is good for her and good for her, so it will be relatively easy to accept.
