Someone who gets better whenever he fails will always outperform someone who responds to failure by getting worse. This isn't something in your DNA, it's something you can learn or unlearn.
I write and think with the following assumptions:
1. All have the capacity to learn beyond the levels artificially set by the institution of school.
2. In schools, time and resources need to be the variables, not expectations.
3. Collective intelligence is more powerful than singular.
4. We need to prepare our students for a collaborative world, not a competitive one.
5. We are at the beginning of a revolution.
6. Failure should be celebrated, provided that it is unique.
7. Listening is more important than talking.
8. Sometimes in order to lead, one has to follow.
9. In order to learn, vulnerabilities need to be shared.
When software -- or idea-ware for that matter -- fails to be accessible to anyone for any reason, it is the fault of the software or of the messaging of the idea. It is an Accessibility failure.
