If you're going through hell, keep going.
You never know what motivates you.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
I can, therefore I am.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
Only the educated are free.
Never complain and never explain.
The role of the teacher is to create the conditions for invention rather than provide ready-made knowledge.
