It does not have to be January 1^st to give yourself a chance to make the most out of your day. Every day is a new day and a fresh start to learn, grow, develop your strengths, free yourself from past regrets or hurts, and move forward older and wiser. Every day gives you a chance to reinvent (重新审视) yourself. It is never too late to change things that are not working in your life.

Each day is a new beginning and a piece of blank paper. How would you like to create your day? What would you like to paint on it? If you wake up in a negative mind, you are more likely to paint a dark picture throughout the day, and your picture will not show hope, happiness and joy.

If you take each day to think actively, and have a positive intention（意图） for how you would like to create your day, how would your life be different? What can daily positive intentions do for you? Every day you will give yourself the gift of an “attitude of gratitude(感恩)”.

Each day is a chance to look at things in a different way. You can experience each day in the beauty of the world－and the beauty of you who are in it! You find yourself changing from “I can’t” to “I can”. With a focus on positive intentions, you feel you are full of power and more like a “winner” than a “loser”.

You pay more attention to the present, and will be more likely to live fully in the present each moment of each day. After all, the past is a great place to visit, but you don’t want to live there! So how about starting each day taking a moment to think of a positive intention for the day?
