Am I progressing?

How can I measure or figure out if I am improving in my journey? I know I have made tremendous gains in my life and my relationship with my incredible husband and kids. I resist the idea that I am not getting better because I fear that I will be complacent. Which makes me act towards complacency. I know failing is not a C, intellectually, but the thought doesn’t fit right. Seems like it’s more like a C.
