The thinking needs to shift from being less about the actual things, to being about the individual user.
It turned out that building mobile software was a lot more like building hardware... where you had 1 shot and you had to get it right, right out of the gate.
We can dream a lot faster than what's possible.
I think that 'system think' is a mindset.
You have to have the definition of what you're trying to do across the system.
No one is going to tell you what to build. If they did, then they should do it, not you.
