The more we think we deserve, the less thankful we are. Saying "Thank you" helps us focus on what we have instead of what we don't have. When we're focused on what we do have instead of what we don't, it does incredible things for us mentally and for others. When we say thank you out loud, when we remember to come back and express feelings of gratitude, good things happen to us, and maybe to others too. Best of all, thankful people are contagious people. The grateful attitude is magnetic.
