A decision is made when there's a perfect correspondence between what lies inside of yourself as a potential direction and what comes as an input from the outside world. Because that's when you become aware of what feels correct. Correct meant as the right thing/action at the right time.
I mean, you recognize in your body what's for you, as soon as it's there in front of you, and that's true for everyone, regardless of one's Authority. What changes is just the timing of the process.
That's a process, in fact, which can be really quick for sacral, splenic, ego and self-projected people, whereas it can take time for emotionally defined people as well as for mental Projectors and Reflectors. Nonetheless, the mechanics behind the decision-making process is always the same.
Now, the point here is that your mind has no clue on when such a perfect correspondence between your inner and the outer world occurs.
So, the first thing to notice is whether there's a pressure or sense of urgency about doing a certain thing at a certain time, as it could be the wrong thing at the wrong time. Wrong in the sense of bringing up resistance.
Beyond that, consider that there are times when somehow you know what's for you, but the timing is wrong. And that means that what you're willing to do is not the right thing to do in that very moment, no matter what. And correct timing can only be established through your Inner Authority.
