It's always too early to quit.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Education must, be not only a transmission of culture but also a provider of alternative views of the world and a strengthener of the will to explore them.
