You want to think about what is the path for my first 10 or 15 employees going to be as the company grows.

Obsess about the quality of the product.

No matter what you choose, build stuff and be around smart people.

At the beginning, you should only hire when you have a desperate need to.

For most software startups, this translates to keep growing. For hardware startups, it translates to don't let your ship date slip.

You can create value with breakthrough innovation, incremental refinement, or complex coordination. Great companies often do two of these. The very best companies do all three.

Stay focused and don't try to do too many things at once. Care about execution quality.
