A little late but being thankful shouldn't be assigned to a day or a weekend...
Being thankful is a mindset that takes constant exercising.
I like to end every day with thinking about things I'm thankful for. I fall asleep in my bed to these thoughts and ya know... it's brought along more positivity in my everyday thinking.
In our world that can get bogged down by what we see on the news and read on social media or feeling like a hamster on a wheel with our jobs and responsibilities... being thankful, being grateful and reflecting on what makes us better and happy- that's how to give thanks.
