Technology should be invisible. When it's working best, you don't even notice it.

Be prepared: When you are 90% done any large project (a house， a film， an event， an app) the rest of the myriad details will take a second 90% to complete.

Look at a day when you are supremely satisfied at the end. It's not a day when you lounge around doing nothing; it's a day you've had everything to do and you've done it.

Never stop learning; the moment you do, you start falling behind.
