You cannot write unless you love reading.

If you're too aware of your own technique you may dissect it to destruction.

Prick your reader's imagination with a stunning fact, or a fresh metaphor, or by turning a familiar fact dizzyingly upside down, or by filtering it through the alien lens of a Martian eye. However useful science may be, and however relevant to everyday life, that is the least important thing about it. Science is, above all, wonderful.
