Destiny is a predetermined course of events usually powered by an irresistible life force. We can intentionally control what happens in the future (to a certain extent). Sometimes, things turn out better than what we could ever imagine. As long as we stay conscious and alert in the present moment; be positive with our mind, thoughts, and actions (even during the bumps along the road); and go with the natural flow; we will fulfill our destiny.
Do you expect to do many great things? Are you destined to be with a certain person and perhaps meant to live somewhere else? When you have the desire and can feel it and believe it, you can make it happen!
