Are I Ching results always independent of one another, or should I look at patterns, too?

I've started tossing the I Ching nearly every day. I've noticed that there is a pattern going on. Every time I've tossed for the last couple of weeks, the Heaven trigram has shown up in the lower position. The only thing that I can come up with is that such a thing indicates an increase in creative power and energy (due to the high number of yang lines), but is there anything else that this might indicate?

I am in a period of my life where I'm undergoing a lot of changes (in the short term, I'm moving; in the long term, I'm changing careers). When I throw the I Ching, I usually look for a general reading, but a couple of times I've had a specific question in mind. No matter what, I still get Heaven in the lower position.

While I don't necessarily believe in divination, I do think the I Ching offers good life advice about staying in touch with your best self and acting in a good way. So can you tell me what this Heaven business might be advising me to do? I'm painting more, but that's pretty much the only creative thing I've been up to lately.
