"Do the right thing" is something I was taught since a child. I also was retaught this for a company I worked for. (Noticed "WorkED"). I was then asked to do the 'wrong thing' related to a client and the account. I could not live with that and quit my job with that company. Value is only worth what someone is willing to pay. If you agreed with a price, even though the larger amount sounds wonderful, stick with your agreement.Like other's have said - who would pay that much for the book? Being truthful to others and to yourself will go a long way. You will be blessed.
