means to an end

I was thinking about this quote today:

Kant was an interesting individual. Yet the above is, I think, a sound principle. I know that I have often felt like a “means to an end” for people – which, alas, I have allowed myself to be so the fault lies with me. And, I cannot control others but only myself.

So for today’s reflection:

DO I use people for the sole purpose of achieving something else?
