How did you know you were ready to start TTC?

My husband and I feel like we’re ready one day and then the next day we aren’t sure. I’ve had some people say if you’re questioning it then you’re not ready and I’ve had other people tell me you never feel 100% ready and it’s just something you have to do if it makes you happy and you’re in a position to handle it. So I want to hear y’alls experiences. How did you/your and your spouse know that you were ready?
