I don’t understand why people make analogies about moving mountains.
It is physically impossible to move a mountain.
You can climb a mountain. Some mountains are easier to climb than others. Some mountains have steps guiding you all the way up. Some mountains take more skill and determination than others. Some take months, even years of training to prepare for.
Some mountains you can climb in a day. Some mountains take a little longer. Either way, you climbed a mountain. Some mountains you climb more than once.
You cannot move a mountain. But what you can do is stand at the top of a mountain and tell the world “Here I am! At the top!”
