Do you think you should pay attention to aspects that has to do with your dominate planet

For instances I’m Saturn, Uranus and Neptune dominate I believe

So should I pay attention to those planet aspecting others?

All planetary aspects have their own meaning and will influence your character and life experience in different ways, so they should all be considered. If I were trying to rank them in importance, I would say look at aspects to your ascendant lord, moon, and atmakaraka (soul planet). But really, it just depends on what area of life you're trying to judge. 🙂
