Taking 'faith' to mean: an effective trust or acceptance of the veracity of certain statements of fact, or the truth of existential claims. I.e. the kind of faith/beliefs that are cardinal to the worldview, or the "ism's" one subscribe to. Eg: "he takes it on faith that Math is sound", "she can sleep soundly in the faith the sun will rise tomorrow", or Wittgenstein's "hinges" below (thanks @Conifold).
I seems to me that there are many conditional beliefs we cary for the sake of day to day functioning. We don't contemplate "cogito ergo sum" everyday, but I could hardly hold down a job without some faith in a future benefit from its proceeds. We all have what we think of as our worldview, but only some actively work to adjust our view. Regardless our efforts to improve, or simply leave most of our understanding to contingency, we all have an idea of what we would call fact and faith.
What would the minimal statement of faith be, could we assert: "I have no faith"?
EDIT: Though I haven't expressly excluded (with reason), religious statements such as "God is doing all of it", those tend to trivialize the question somewhat. So I'll request that answers on the religious vein be kept to something that are at least to some degree rationally rooted, i.e. it can be reasoned about within the broader context of 'purely rational' answers.
