You can’t see the end from here. Neither could anyone who ever did anything worth remembering.

Not knowing how it turns out is the normal condition, not a sign you planned badly. Every person whose story you know in finished form was, at your point, working without the ending. They had a direction and no view of the outcome. The certainty you see in them was added later by whoever told the story.

Stop waiting for the fog to clear before committing to anything. Choose the next step on what you know now, and set a point to reassess, say in three months. Acting while uncertain is a skill that develops by use.
