Can you prepare for contingencies yet still work from the vortex?

I don't see how you can, from a Law of Attraction point of view.

As you prepare for an out-of-the-Vortex Plan B, you are (because of where your focus is going) making Plan B more likely to manifest i.e. you are decreasing the purity of the vibration of Plan A.

The only way in which the preparation of a Plan B would help Plan A is if it made you feel better about Plan A...but that's something you have to feel carefully emotionally within yourself on a case-by-case basis, not a hard and fast rule.

How do I address possible problems to prevent them, yet feel good doing it?

I think the ideal approach would be to focus entirely on Plan A and clean up how you feel about things that you believe might get in the way of it.

" But is there a way to do that and look out for what could go wrong? To prepare for possible problems so they do not occur, yet be in the vortex and feel good?"

as stingray said - no.

because in the vortex there are no problems at all (to prepare to).

but if it feels like a must you can try change the words: "wrong" into--- "interesting"

and "fear" into --- excitement

failing ---- i never fail no matter what

cannot handle that...- i can handle that, there are no mistakes, just experience.

etc.
