Selfless ownership
Own your work, but don't miss good collaboration opportunities to make it better.
Be pragmatic
There's no silver bullet, ever. Choose the right trade-offs for each situation.
Align often
Write plans, make prototypes, build in pieces. Share it all frequently.
Measure and iterate
Measure your impact, iterate to improve it.
Be demanding, but understanding
Expect the best from your team, but prepare for the unexpected speedbumps
