I see it like someone who's a great teacher, respected by her coworkers, but is eventually promoted to "Prinicipal". That's not what she wanted when she became a teacher, it was just thrust upon her, and she never gets to teach again.
Janeway aspired to be a Starship Captain... and Mulgrew, like many of us, fears in the mind of the writers any promotion beyond Captain is in effect... a demotion since she'll "supposedly" never captain a ship again. (Kirk did Kate!)
In effect, Janeway "was" Maureen McGovern's Sailor... who was brought home. Trouble is, once the sailor has been to sea, they really can't stay home anymore.
"I could have been a Sailor"
I'm a happy woman, I made my choice in life
I chose to settle down, I chose to be a wife
And I take pleasure in my quiet hearth, And happy home
I never gave my heart, Its chance to roam
I could have been a sailor, And sailed the seven seas
The wind in my face all day Can you taste the salty breeze?
I could have been a lover, Watchin' waves before me part
But I settled for safer harbors Of my heart
I'm a lucky woman, I'm the envy of my peers
Never ask for favors, And I never show my fears
Surrounded by too many friends, I am a one-man band
With all the trappings of A life lived second-hand
I could have been a sailor, Rollin' through the night
My sails before the wind, And the stars my only light
I could have been a dreamer, But dreams just fall apart
So, I settled for safer harbors Of my heart
And I take pleasure in my quiet hearth, And happy home
I never gave my heart, A chance to roam
I could have been a sailor, And sailed the seven seas
The wind in my face all day Can you taste the salty breeze?
I could have been a dreamer, But dreams just fall apart
So, I settled for safer harbors Of my heart
I settled for safer harbors Of my heart
