One of the quickest ways to change your outlook on life is to adopt a spirit of gratitude. Take the time each day to thank God for the blessings in your life. Some days that blessing may something as simple as laying down to go to sleep in a comfortable bed at the end of a long day. Other days, your list may be overflowing. Taking the time to say "thank you" will lead you to pay more attention to the good things in your life, and that can't help but lead to a more positive outlook.
