Needless to say, the person who got lost didn't just end up in the wilderness with one step. His being in the wilderness was a result of the very first step he took off the path, and his continuing on that trajectory, without correcting his first, tiny misstep.
***
Entering the wilderness of life does not happen with just one step. At a moment of temporary darkness, our focus veers from the light and truth of Torah, and so long as it is dark, we continue taking steps away from the Path of Life, G-d forbid.
When the light of Torah illuminates our lives again, the error is discovered, as does the direction and path of return.
One step at a time.
