Only the educated are free.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
You never know what motivates you.
The wise does at once what the fool does at last.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
If you think you can do it, you can.
What is research but a blind date with knowledge?
