Seth Godin posted this.  He bought something. It didn’t work.
Employees at the store promised to take care of his problem.
Not one did.

I don’t know which is worse.
To never promise a client you’ll do something they want from you or make a promise but never fulfill it

OK, I think I know.
To make a promise to your client and fail to keep it.

In both cases your client doesn’t get what she wanted.  But when you make and break a promise . . . your client loses something else –– confidence in you and the value of your relationship is eroded.

KEY POINT:
Keep your promises to clients.  Pretty simple, isn’t it?
