Sometimes It's Hard to Be Grateful

Sometimes and in some places it's hard to be grateful - so remind yourself.

Put a sticky note in your car that says, "What do I have to be thankful for?"
That way, when you're setting out on onerous errands, stuck in hellish traffic, or coming home to chaos, you have the chance to pause and reflect on that which you do consider a blessing: your health, the loved ones you're shopping for, your nice warm coat, whatever.

And you can write these blessings in your gratitude diary later on.
