Be kind whenever possible. It is always possible.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
Know or listen to those who know.
It's always too early to quit.
There were no PCs when I started programming on computers.
