Whatever obstacles or challenges you may encounter along the way, meet them with curiosity. Embrace them and examine them by asking small questions. Don’t let fear, pride, or impatience deprive you of the opportunity to ask. As Carl Sagan once said, “There are naïve questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand the world. There is no such thing as a dumb question.”
