>>6 It is a lot of thinking :). I think that is what makes haiku so meaningful - you have an idea that needs to be stripped down to the bare bones of it, but still able to convey the meaning of it. It requires thought and strategic use of language. It's hard to write a haiku by just writing what you think of in the moment, that is more like free form poetry.
**Side note, rhyming is not the the norm, but as far as I know it is allowed.
So if you cut "the" from your last line I could continue:
The day born, world torn. (5 syllables)
To create, one must destroy (7 syllables)
preconceived notions. (5 syllables)
**Note the punctuation in the second and third lines. It is to be one sentence that I broke up so that the second line has 7 syllables and the 3rd line has 5 syllables.
Hope this helps.
