Think. Vacillate. Ponder. Mull. Compute. Process. Wonder. Ruminate. Fantasize. Muse. Reflect. Deliberate. Consider. Meditate. Contemplate. Day-dream. With all that you do, always remember to THINK. Let your mind stretch its legs, saunter about, examine fallen leaves and turn them over in its hand, and in return you can cup the waters of intellect in your palms and drink.
