Destiny vs Free Will

I think that destiny and free will are on a spectrum.  There are some choices that a person makes that can decide their destiny from that point in.  For example, a person that chooses to do a stupid stunt or take a risk that then paralyzes them would be destined to not achieve in an athletic field.  In this case a choice would lead a person to a different destiny.  One could always make the arguement in this situation that they were just destined to mess up and become paralyzed but I think that is invalid.  Honestly this arguement is impossible to ever decide because nobody will ever be able to tell if destiny is real.
