Physics changes, but reality stays the same
You can stop anything but a person with a good attitude.
There are no failures - only feedback.
Learning is about looking at things differently, making your life a little better everyday.
It's an attitude that has to do with curiosity, with wanting to know about things, wanting to be able to influence things, and wanting to be able to influence them in a way that's worthwhile
If it's worth feeling bad about, it's worthy of amnesia.
