I personally don’t like the comparison with movie director that much because it seems that God is directing us constantly and given our free will is not necessary like that. To me God is more like the created of a cartoon comic strip, he creates the characters, creates the environment and creates the entire set up and the rules by which the cartoon will run but the twist is that he gives the cartoon a life of its own. Instead of the cartoon creator having to write an episode for the cartoon everyday he just brings them to life and lets them develop their own story. He knows the future not because he wrote a previous script stating what is happening to each character but because he created each character and has the ability to read and know each character to perfection which gives him the ability to know without failure exactly what each character is going to do. We do have free will and we ate capable of taking our own decisions what happens is that the extent of God’s knowledge of each of us so big (he knows us even better than our own selves) that he inequivocably can know how we are going to react and how are we going to act in the future.
Blessed John Henry Newman said we all have a purpose. We were all made for a reason. Not just dumped into life (though I thought your post was imaginative).
If each person truly discerned their path then all would find their reason for being. Otherwise, ‘reason’, would not exist. That path of life is a path of truth which we can turn away from, or walk along. And when we don’t walk it or we move away, He leads us back, and heals the damage. It is our choice to be open to it and to go back when fallen.
Take absolutes. We have Our Lady. Her path in life was Mother of the Second Person of the Holy Trinity. Take the saints, they had roles. Or the Popes. They all have and had a purpose. So if there are paths for a few, there will be paths for all.
The difficulty, is the worldly view of what constitutes a particular, a special, path. Most envision something fantastically outrageous. But the very reason Our Lady and the saints were chosen to be who they were to be was because they were humble, of their humility, and because they pursued life with, as St. Therese said, “holy daring”. Their delight was in the Lord. And this living out in their lives of this delight exalted them, the lowly. Similarly, those who wish to be big in the world, the princes, are brought down - as the Our Lady speaking the
Magnificat said - because they follow their owns wills.
The other difficulty, leading on from expectations, is about what is considered grand in Heaven. Consider the
Widow’s Mite. What the worldly deems as important and what our Creator thinks is important are not necessarily often the same. Your part in life, and reason for being, might be very small things to you and to the world, but to our Creator, these little things might be of huge importance.
Last, the living of a perfect path is fraught with difficulties, but it is not us who can achieve the impossible. It is only relying on help that we can. So often on our paths, we will take roundabout routes, or say “no” even - as Jonah did, Moses didn’t always trust, and many others had difficulty understanding - to what our Creator has in mind, but He can and does, if we let Him, put us back where He wants us, in our hearts, so we can be redeemed, because we have already “been bought and paid for”.
