We have an obligation to read aloud to our children. To read them things they enjoy. To read to them stories we are already tired of. To do the voices, to make it interesting, and not to stop reading to them just because they learn to read to themselves. Use reading-aloud time as bonding time, as time when no phones are being checked, when the distractions of the world are put aside.

People who believe they'll be happy if they go and live somewhere else, learn it doesn't work that way. Wherever you go, you take yourself with you.

No, look, there's a blue box. It's bigger on the inside than it is on the outside. It can go anywhere in time and space and sometimes even where it's meant to go. And when it turns up, there's a bloke in it called The Doctor and there will be stuff wrong and he will do his best to sort it out and he will probably succeed cos he's awesome. Now sit down, shut up, and watch 'Blink'.

Whatever it takes to finish things, finish. You will learn more from a glorious failure than you ever will from something you never finished.

Entropy and optimism: the twin forces that make the world go around.
