The decisions you make are based on the now
The decisions you already made were based on the now of a time gone by. They are irrelevant to the now now.
Making a decision on what might happen in the future is a risk to your future now. That doesn’t matter now, which doesn’t mean it won’t in a future now either.
Dealing in nows means focusing on the current moment and all but ignoring every other moment. It means working at the best of your knowledge in this moment, and not worrying about things in the past or the future that don’t exist.
They may have existed in the past, and they may exist in the future. But is that a problem for now?
