Do what you say, say what you do.
Your word is the one thing that no one can take away. Follow up on your own, organized timetable.
Over time, I've found that something as simple as being a bit disorganized can cost me money -missed opportunities -- by follow through that is too late.
People - prospective clients and business partners form an opinion of you when you do follow up, and when you don't.
Suggestions -
Go through your Outlook or contact manager - who have you not talked to lately?
Do you have a "next action" for every interaction? Be sure to document and then FOLLOW UP. I use Outlook for this.
