Be kind whenever possible. It is always possible.
Who seeks shall find.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
After a storm comes a calm.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
You never know what motivates you.
Quality is not an act, it is a habit.
There's a lot of interest from the medical community on how things develop in microgravity, and the hope, later, that is expected to apply to what the changes are in humans as well.
