In this challenging year, it may be hard to remember the last time it didn't feel like your plate was full. When we're so busy, it's easy to overlook even important things — like the people who are making a difference in our lives.

As we get close to Thanksgiving, take a moment to reflect on the times this year when you've been elevated by the support and kindness of others.

Maybe this makes you think about the friend or former colleague who always seems to know when you need a cheerful call or text message. Or the boss who still finds the time to listen even though you know her schedule has gotten busier. Or your family members who have kept a good attitude despite changes in your routines.

Just by thinking about the people you are grateful for, you'll feel less stress. And who couldn't use that right now? But don't stop there. Let these people know how they've made your life better and how much you appreciate them. Your expression of gratitude will lift their spirits. And, again, you'll benefit, too. Positive psychology researcher Martin Seligman found that when people shared letters of gratitude with someone they had never properly thanked for their kindness, they immediately became happier — and stayed happier for the next month!

In my own life, I want to thank my sister, brother, aunt and cousins who have really gone the extra mile for me this year. Who is on your personal gratitude list? And how will you let them know about the important difference they have made for you?
