Out of Control

I have been so busy meeting with people that I have not been very good at sending thank you notes and emails. Nor am I able to remember who I have sent them to.

I shared this dilemma with my Master Mind group on Friday and they agreed that a thank you is always appreciated, even if it is late or a duplicate.

My question is, what system do you use when you are so busy all week that you don't always have time to send those notes immediately. Do you just make a list of people to thank or do you go back through you calendar to jog your memory. I badly need a system and maybe it is as simple as a list.

Help me out. I am in a little bit of chaos!
