Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper. ~Albert Einstein
Destiny is a road map that predetermines the kind of life we will have. Based on Einstein's premise, destiny is our fate, the road assigned to us by God. Hence, no matter how we try to deviate from such road, we will still arrived at the designated place whether we like it or not.
God has many ways and miracles. The human intellect is not the absolute tool that can shape the unknown but prayers and faith in our creator is the best way to face the future with confidence.
