Never complain and never explain.
Always desire to learn something useful.
The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
After a storm comes a calm.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
