If you think you can do it, you can.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
Expect problems and eat them for breakfast.
Well done is better than well said.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
This truth is a remedy against spiritual pride, namely, that none should account himself better before God than others, though perhaps adorned with greater gifts, and endowments.
