Embrace every challenge you have, every person you meet, every place you visit, every task you succeed at, and especially those at which you fail. You will learn from them all. You'll learn about the world at large and about other people but most important, you'll learn about yourself.
Don't look over your shoulder and don't use or abuse others to get ahead. Keep your eyes focused on your goals and keep working for what you believe in and what you want to accomplish.
Seize every opportunity you have to learn. Keep your eyes and ears wide open and seize life — don't let the moments slip through your fingers like a fistful of sand. Be your own teacher. Let life write your textbook.
