You are saying that you will "Seize the day". This means that you will live the day to the fullest, and do all the things that you are capable of doing. It means that you won't waste a moment of the day, and that you will try to experience and enjoy everything that the day has to offer. When you "seize the day" as a mantra, it is a dedication to living your life to the fullest possible potential.
