Almost all self-help books mention the power of gratitude. Showing appreciation for simple joys and blessings is an easy way to lift your spirits and set you on a path to focus on the positive things in your life. In the book, Read This for Inspiration, author Ashley Perez says an easy way to begin to incorporate gratitude into your life is to change the home screen photo on your phone to a moment or person or thing that brings you joy. She also recommends you change that photo every week. This constant reminder will pop up every time you reach for your phone. Changing it every week will force you to look through your photos making mental notes of all the things and people that bring you happiness.
