Unable to answer this for certain. At least 5 years of part time study and practice.

I can say though, that...
The journey was at first an ascent up an apparently modest hill, which I assumed I'd be more than capable of scaling.
I approached what I thought was the crest, only to realize there was a higher crest in the distance beyond.
And you can guess what happened as I approached that apparent [second] crest. Yep, I'd totally underestimated the enormity of the task and still do not know to this day exactly where the summit is or how far.
The path up is neither straight forward nor direct. There are dead-ends and unscalable sheer faces, so setbacks will likely occur. The weather can set in and it's best during these times to make camp for the night and rest until the next day. The sun does shine from time to time and looking back down the path does reveal how far one has climbed.
There are others making the same journey. Upon hearing only their voices, it's not clear how far they have advanced. The gales and craggy rock faces distort their sounds, but sometimes wisdom is gained and mistakes avoided by listening. And those on the lower faces can be of aid to those still residing in foothills.
Some good folk holla down from the top with helpful advice and hints as to the route and how to go about scaling the, now apparent vast mountain. Their perspectives are different to ours and there's only so much they can do to help. They'd perhaps throw down a rope if there was one long enough or if they even knew where we were.
We all have to take our own unique paths. Some take much longer paths than others. Some die on the face, some fall off, some are swept away by avalanches, some make it only to the foothills, some quit on the final crest before the summit. And then... there are the ones who make it all the way, who experience the panoramic views, who can see far and beyond, who understand the structure of the mountain for what it is, who can see the weather forming from above and the landscape all around. They don't know everything there is to know (and there are still unseen faces to explore), but they know enough and have acquired the sure-footed qualities necessary to remain atop the mountain.
Time to dig a snow hole. The ascent continues Monday. Is that the summit I see...
