The landscape changes, so enjoy it: of course, you have to have an objective in mind - to reach the top. But as you are going up, more things can be seen, and it's no bother to stop now and again and enjoy the panorama around you. At every meter conquered, you can see a little further, so use this to discover things that you still had not noticed.
