Learn how to live.
Laugh in the sunlight. Run through the grass. Explore new things. Say no when you mean no and yes when you mean yes. Speak the truth. Try new foods. Jump high. Scream loud. Use your imagination. Go as fast as you can. Go as far as you can. Test your limits. Take naps. Share. Give big hugs. Get your feet dirty.
