If you can dream it, you can do it.
Well done is better than well said.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
I can, therefore I am.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
Wherever you are - be all there.
If you're going through hell, keep going.
