Timing is more important for Ultimas, since they have short-term state-focused effects. Generally 1-2 hours before the situation where your planning to apply it.
For major programs, timing and order may matter less in the big picture. The metric I’d advise to keep foremost in mind is Action.
In this phase of your life, where do you take the most action? And where do you intend, wish, or plan to take the most action. I’m talking independently of any subliminals.
Those areas should be considered as priority areas. They’re going to have more immediate effects.
Areas of your life in which you’re slower or more tentative with action can also be addressed with subliminals. But it’s reasonable to take a longer-term and more patient approach with those. Building up over time.
This principle can help with planning out your stack and your play ratios and intervals within your stack. (For example, no need to go crazy playing something all the time right now if you know you’re not going to take much action on it. Instead, maybe play it once a week consistently and start planting those seeds. In the meantime you can pay more attention to feeding other more active areas that can, in the immediate time frame, also contribute to that longer term goal.)
