A person’s life typically feels normal to them, right?
Sure, it may be more or less average, but you have to have something to compare your life with (and the time and a reason to stop and compare it) to notice how much it is or is not so ordinary.
Even then, as your everyday lived experience, it is your normal.
The problem – and the potential – with life nowadays is that we see many examples of the extraordinary, and we have ideas (notions, fancies?) of ourselves and our lives as we wish they (and we) were.
