Remember how you were always told to count your blessings? It was to get you to focus on what positive things were in your life, rather that dwell on the negative.

Listing three or more things that you’re grateful for each day is one of the best ways to begin to become more positive and optimistic. It doesn’t make the difficulties go away, but by focusing your attention on better things, you feel better and are able to deal with challenges easier.

Studies are now finding that using this simple technique for just three weeks actually still affects a person positively six months later. The mind has been trained to look for good in the world. Not only does this increase happiness, but it also can help those with depression.

When things look darkest, look for some good in your life. Use it in your personal and professional life. Practice it when you feel down, stressed or pressured. You’ll be training your brain to work at more positive outcomes.
