"...then good." WTF?
Why would you want to "hide" your intent from your CC and SR?
I am frank and open with my guys, my SR, and everyone in between.
This year alone, I've gotten 4 of 5 guys to their #1 choice (not all were my #1 recommendation for them) of assignment or school, and got the 5th an option he was content with.
That's not going to happen if you keep secrets.
All your career choices are valid. My job is to show you the alternatives to your career choices, then help you on your chosen path.
How can any other method possibly work in your favor?
Don't keep secrets, guys...tell your CC what's important to you, and what you want to go do next, and the follow-on...then let the CC work Magic for you.
