Gratitude

There are some excellent mindfulness apps online like

The following advice for people of all ages comes from https://kidshealth.org

Notice the Good Things in Your Life
Start to notice and identify the things you are grateful for. Tune in to the small everyday details of your life and notice the good things you might sometimes take for granted.

Once you’re aware of the blessings of everyday life, the next step is to savor them.

Savor the Feeling of Gratitude
There are moments when you naturally, right then and there, feel filled with gratitude. These are moments when you say to yourself, “Oh, wow, this is amazing!” or “How great is this!”

Pause. Notice and absorb that feeling of true, genuine gratitude. Let it sink in. Soak it up. Savor your blessings in the moment they happen.

Express Gratitude
Expressing gratitude is more than courtesy, manners, or being polite. It’s about showing your heartfelt appreciation. When you thank someone, you’re also practicing the first two gratitude skills: you’ve noticed something good, and you’ve genuinely appreciated it.

Try this:
Show your appreciation to someone who did something nice.
 Say: “It was really kind of you to…,” “It really helped me out when you…,” “You did me a big favor when…,” “Thank you for listening when…,” “I really appreciated it when you taught me…,” or “Thank you for being there when….” You also can write your gratitude in a letter.

  • Express gratitude by doing a kindness.Gratitude might inspire you to return a favor, or act with kindness or thoughtfulness. Or you might see a situation when you can “pay it forward.” Hold the door open for the person behind you, even if it means waiting a little longer than you normally would. Do someone else’s chores without letting the person find out it was you. Notice how you feel afterward!
  • Tell the people in your life how you feel, what they mean to you. You don’t have to be mushy or over-the-top. We all have our own style. But if you say what you feel in the right tone at the right moment, even a simple, “Mom, good dinner. Thanks!” means a lot.

True gratitude doesn’t leave you feeling like you owe other people something — after all, if you’ve done someone a favor, you probably don’t want the person to feel like you expect something back in return. It’s all about feeling good and creating a cycle of good.
