- What is the problem to be solved?
- How are we going to solve it?
- How can we test that the thing we built matches what we set out to build?
- How will we know if it’s working?
“Are you sure?” is something humans ask all the time. If you go to an ethical plastic surgeon and announce, through drunken tears, that you want a new nose, new lips, new hips and a skin peel, all at once, she’ll not only ask if you’re sure, but she’ll send you home to think about it first.
When building habits, choose consistency over content.
The best book is the one you can’t put down.
The best exercise is the one you enjoy doing every day.
The best health food is the one you find tasty.
The best work is the work you’d do for free.
