You aren't at the beginning anymore—that fresh, naive optimism is gone. But you aren't at the end yet, either. You are in the thick of it. The middle. The grind. The place where most people quit.
You were in the thick of it. And you completed it.
The greatest completions happen in noise, in stress, in imperfection. If you are waiting to leave the thick of it before you finish, you will never finish anything.
