If you can dream it, you can do it.
It's always too early to quit.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
If you think you can do it, you can.
I can, therefore I am.
Never complain and never explain.
Learned men are the cisterns of knowledge, not the fountainheads.
