Absolutely. This is something I've been trying to do on a daily basis.
Being grateful for the smallest things we often take for granted can completely change your mindset.
For example, I actively remind myself that I am grateful to have a roof over my head, a warm bed to get in at the end of a day, a job that helps to pay my bills, clean running water, food, family, health.
Life is great if you're grateful for everything it brings!
