Without hard work, nothing grows but weeds.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
If you think you can do it, you can.
Always desire to learn something useful.
I can, therefore I am.
Who seeks shall find.
Either you run the day or the day runs you.
Know or listen to those who know.
Never complain and never explain.
A serious and good philosophical work could be written consisting entirely of jokes.
