Be thine own palace, or the world's thy jail.
Well done is better than well said.
I can, therefore I am.
If you think you can do it, you can.
After a storm comes a calm.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
It's always too early to quit.
If you can dream it, you can do it.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
