Awkward phrase starting with 'therefore' - need help revising

"Therefore, it wasn't necessary for me to find my keys."

This phrase sounds a little awkward. I wanted to use "necessary" in some way (maybe, I didn't necessarily need to find my keys) but every phrase I tried didn't sound right. Could someone help me revise it?

I don't know how the rest of your paragraph goes... but maybe...

Finding my keys was not necessary ?

Thanks, it helped a lot.

Awkward sentence using "Juncture"-Help revise?

Sentence is: I am at the last juncture in my life when I can successfully adopt a new name.

I am speaking figuratively, but I don't know how to use "juncture" without using "when" which makes it sound a clunky. Help?

I think it sounds fine, but you might be able to modify it to:
In my life I am at the last juncture where I can successfully adopt a new name

when sounds more sensible as you are talking about the time in your life, but I believe you could substitute where if it sounded better to you, speaking of the juncture as a place in time

Yes.. it is bad to use juncture with when. Use juncture with where, because it is a place.

Also, juncture refers to where things join. Is it really the best word to use?

I face my final opportunity to change....
maybe like that?
