Am I fooling myself?

Hi there,

So I am feeling resistance towards my job. In my private coaching session I was asked “why are you doing it?” and “are you doing it for reasons that matter to you or because someone else would think better of you”?
Now when I explain the reasons why I am doing it I can make a list of all the reasons that seem to being compelling me to do this job. But how can I be sure that I am really living from that why, that that is the why (and so the model) I am really operating from, and I am not just bullshiting myself (=doing from different reasons/different model)?
