Thanks Paul. Thank you's are huge! I work for a non-profit and we have many volunteers. I make it a point to always say thank you- every time they come in, especially for the ones that have been faithful volunteers for years. The one point I would add is to make sure the thanks is sincere, and does not come across as the 'token' thank you. Stop and look them in the eye if possible and then give them the thanks. Or sometimes a short note.
Thanks for the reminders today.
