I've seen the mountain top, and I grew very tired both on my way up and on my way back down. Still, while I was there, at the precipice I found it awe inspiring. I found it lovely. I found it beautiful. And might I say, a tiny bit sad. I guess my point is, it doesn't matter if you grow tired. It matters that you keep going. In fact, that may be the most important part of the journey.
Still, your thoughts are interesting. Maybe you could make it longer by describing some of what I just described.
Just be careful not to make it sound too much like that "Climb" song by Miley Cyrus! lol
