Here are some of the most interesting things we've uncovered this past week:

How does Elon Musk's Tesla team make decisions?  They focus on "first principles."

The benefit of “first principles” thinking? It allows you to innovate in clear leaps, rather than building small improvements onto something that already exists. Musk gives an example of the first automobile. While everyone else was trying to improve horse-drawn carriages, someone looked at the fundamentals of transportation and the combustion engine in order to create a car.

Why quitting is for winners.  Some really great questions to answer when you're at a crossroads in your career.

Choosing speakers for your next event?  First, read what Whitney Hess has to say about transparency and gender equality at conferences.

So true:  "[T]here’s no prize for best 19th Century enterprise still operating in the 21st Century."

Basecamp's David Heinemeier Hansson suggests we drive development on projects based upon their worth to us:

That’s what proposing a budget based on worth helps you with. It focuses the mind on what assumptions we can challenge or even ignore. If we only have 5 weeks to do something, it’s just not going to work to go through the swamp to get there. We have to find a well-paved road.

When designing projects, don't forget to focus on the senses.

Pick a date. It can be far in the future. Too far, and we'll all know that you're merely stalling. A real date, a date we can live with and a date you can deliver on.

If your project can't pass this incredibly simple test, it's not a project.
