Express gratitude to your family members and friends. Many of us take the people closest to us for granted, and show far greater appreciation to strangers who have done us a favor than to those who have undoubtedly done us hundreds.

If those close to you have made it known that they do not feel appreciated, resolve that — for a specified period of time, perhaps the first week of each month &mdash you will treat your spouse, children, siblings, and parents with the same courtesy and gratitude you extend to strangers.
