"I am not growing in my current role."
This is the statement I hear most frequently during 1:1 mentorship conversations, both inside and outside the organization.
One technique I suggest to foster self-reflection is this:
Pickup a key artifact that you developed 6-9 months ago (e.g. proposal, design) and compare it to one that you have delivered just recently.
You will be surprised at how your perspective about your own growth will likely shift once you do so.
P.S: I just did this with my LinkedIn writing - looking at a post from November '22.
