The wise does at once what the fool does at last.
Always desire to learn something useful.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Only the educated are free.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
