Inspired by legendary Agile manifesto and my own experiences:
1) Having the talent to see through & anticipate failures over finding them later
2) Using machines/tools/humans as slaves to get things done over becoming their slaves
3) Common sense over conventional wisdom
4) Questioning every assumption & requirement with respect over sheep-walking
5) Doubting (with respect) over trusting or hoping for the best.
6) Being reasonable, firm & constructive over being the opposite
