How does the author develop the idea that working at Tri-Valley Hospital was a good experience for the narrator? by telling the reader that things didn't go as planned for the narrator, but they turned out well in the end by showing that the narrator chose to become a doctor and work at the hospital by explaining to the reader why the narrator doesn't believe that everything happens for a reason by sharing details about how the narrator met his wife and how they built a life together

I left in a French steamer, and she called in every blamed port they have out there, for, as far as I could see, the sole purpose of landing soldiers and custom-house officers. I watched the coast. Watching a coast as it slips by the ship is like thinking about an enigma. There it is before you—smiling, frowning, inviting, grand, mean, insipid, or savage, and always mute with an air of whispering, ‘Come and find out.’

Explanation:

This one was almost featureless, as if still in the making, with an aspect of monotonous grimness. The edge of a colossal jungle, so dark-green as to be almost black, fringed with white surf, ran straight, like a ruled line, far, far away along a blue sea whose glitter was blurred by a creeping mist. The sun was fierce, the land seemed to glisten and drip with steam. Here and there greyish-whitish specks showed up clustered inside the white surf, with a flag flying above them perhaps.

the first proposition is to question economic materialism and victorian christianity. the lines are:

“it moves us not.—great god! i'd rather be

a pagan suckled in a creed outworn; ”

wordsworth is stating that nature no longer interests mankind, that the latter is not “moved” by it and explains that ancient western paganism had a more positive attitude concerning nature since it lacked the perv erted judaeo-christian interpretation of having received the world and all its animals and elements from god to use as we , instead of humans actually being not only part of nature but its wardens, meant to appreciate it and protect it.

the next lines are:

“so might i, standing on this pleasant lea,

have glimpses that would make me less forlorn;

have sight of proteus coming from the sea;

or hear old triton blow his wreathed horn.”

wordsworth here make it very clear that by actually looking and contemplating nature, human beings would reconnect with happiness, serenity and purpose. the use of mythological figures is quite evocative as well, proteus is a greek mythological god of the changing sea. he personifies the sea that changes, which symbolizes the way nature changes and inevitably can change to be destructive not only due to natural causes but to human pollution. furthermore, the sea is even more symbolic since all life originated in the sea so it is not only our past but our future since no life form in our planet can survive without water and if all water is destroyed in earth all life will be gone as well.

he then uses triton which is symbolic of the synthesis of both nature and mankind. triton is a mythological greek god that has the upper body of a man and the lower body of a fish (a merman). this human fish duality evokes the fact that humans are not only human but also part of nature, the fish tail representing nature. the main attribute of this god was that he used a conch shell as a horn to calm the roaring seas. in other words, triton uses nature through science for the benefit of human sailors who risk death during tempests. with the use of such metaphor, wordworth is conveying the message that human technology   is supposed to use nature to preserve nature and thereby humanity as well.
