I received the following email from The Secret Daily Teachings, and liked it a lot:
"Every single day, no matter who you meet in the day - friends, family, work colleagues, strangers - give joy to them. Give a smile or a compliment or kind words or kind actions, but give joy! Do your best to make sure that every single person you meet has a better day because they saw you. This might sound like it is not connected with you and your life, but believe me it is inseparably connected through cosmic law.
