"Decisions Determine Destiny"

I think it means to determine of what do you want to be like Thomas S. Monson and to do your best of what you want to be and show how the best can you be! Destiny is to be your best of what you can be and show how you can be the best. Decision is on how your life is the best or what you choose to be in your life and like there's a good or a bad life. People stayed determined to be the best of what they are and what they are to become the best. Thomas S. Monson always says "Choose your love, Love your choice. Courage, not compromise, brings the smile of God's approval." to see how people can be to themselves.
