You have a degree in marine biology.
. . .and?
You are moving to a land locked state.
. . . so?
Are you going to throw away your career?
. . . maybe.
(In reality no, but I'm not going give you that comfort. You clearly don't understand how modern science works)

Career is not the best way to measure a successful life.
I stand firm to your confused glare.

I went to college at 18 and decided "marine biology".
. . . why?
It's cool.
I had one class in oceanography.
I have never held a fish before.
I had been to the ocean a few times.
At 18, I based my life on "It's cool" and no one thought twice.

Now, I'm pushing 30. This year I got married to my bestfriend of 4 years, we bought a house, and want to start a family.
. . . and you are asking "Are you sure?"

I have been thinking and planning this for  years.
I have lived through 2020.
I am more sure of this than anything in my life.

So, if you don't understand?
If you don't approve?
Agree?
. . . It's cool.
