Be thankful every day not just on Thanksgiving.
Throughout the day today or tonight before you go to bed write down all of the things you said you are thankful for. Look at your list first thing every day to remind yourself of everything good in your life. You'll start your day on a positive note with staying power. If you've watched the Secret or read the book you know the power of gratitude. Being thankful will bring more positive things into your life.
Keep your list handy for when things aren't going so right. Pull it out for a little refresher that life is good.
