"This moment is the ultimate moment of my life until now." How can you say this? Because this is the moment that you've been practicing for your entire life. Everything you've ever studied and everything you've ever learned is now stored in your brain. The wisdom of your life experiences has reached its highest point (so far) at this very moment.
This moment is made up of all that you've ever learned and done. All the moments of your life have added up to this very moment. So since this moment is so special, make it really special. How do you do that? With your self-talk. With your thoughts. With the way you draw upon all of your skills and talents and wisdom. With the words and the actions your mind tells you are the best for this moment.
Just consider this moment special, and it is. And this is not only true for this moment. Rather, it is true for every single moment, for as long as you live. The present moment is the culmination of your life until that moment.
At this moment and each moment, you get to choose your thoughts, and your words, and your actions. Make wise choices. Make choices that you will look back on later and say, "I am glad that I made those choices."
