Destiny is not a fixed marker, to say so, means there is a source deciding what happens, and this is not true.
Fate, or It Was Meant to Be are lame excuses and reasons for events. We control and govern our lives not any floating or fixed identity.
We live in a time of influence from concepts and ideas from people with little or no knowledge of how life works. Well, in fact, no one knows how life works but it is certainly not predestined.
Take a hold of your life and know you hold your direction, you hold the way in which you want things to happen. Mishaps happen but that is what life does, it is not a destiny.
Be in charge of your life and move it in the direction you want, keeping in mind obstacles do happen and are a part of life.
