I like to listen. I have learned a great deal from listening carefully. Most people never listen.

God lets everything happen for a reason. It's all a learning process, and you have to go from one level to another.

Change your life today. Don't gamble on the future; act now, without delay.

Never give up. Today is hard, tomorrow will be worse, but the day after tomorrow will be sunshine.

People only see what they are prepared to see.

We are drowning in information but starved for knowledge.

Perplexity is the beginning of knowledge.

You teach best what you most need to learn.

The possession of knowledge does not kill the sense of wonder and mystery. There is always more mystery.

Once you learn to quit, it becomes a habit.
