I suggest that you make gratitude a part of your day. Just as you may pray or meditate or do positive affirmations, try to also include some things that you are thankful for. Spend 5 minutes every morning listing things or thinking about things that you can be grateful for. Add dinner, you could go around the table and have each person say one thing that they are grateful for that happened that day. This is a great way to pass gratefulness on to another generation.
