Congrats!! I remember your earlier posts about your current job situation and I'm so happy this worked out for you. Haven't had a chance to read the whole HBR article but have a feeling it will resonate.
I have gotten the advice before that one way to get ahead in your current job, even if you don't want to leave, is to interview for another job (even if it's not one you will definitely accept). This may be career-specific but by doing this, your organization is forced to consider how much you mean to them. I didn't really think I was valuable enough to my old institution for this to hold true, but it did. When I told them I was leaving, I got offered some different options for them to hold on to me.
Anyway congrats! And let this be a lesson to all of us not to underestimate our value.
