some interesting differences :)

Long work vs. hard work (http://sethgodin.typepad.com/seths_blog/2011/05/hard-work-vs-long-work.html)
- long work is working for long hours [12hours ....]
- hard work involves risk taking
- long work doesnt result in failure
- hard work can result in failure.


The flip side (http://sethgodin.typepad.com/seths_blog/2011/04/the-flip-side.html)
- innovation can result in failure; [other side of the coin is 'success']
- if you say 'failure' is not an option implies you are saying innovation is not option!

teachers, coaches and mentors (http://steveblank.com/2011/04/19/mentors-coaches-and-teachers/)
- If you want to learn a specific subject find a teacher.
- If you want to hone specific skills or reach an exact goal hire a coach.
- If you want to get smarter and better over your career find someone who cares about you enough to be a mentor.
