We are children of God; but that fact means we are as varied in our destinies as mortal children of human parents.
As the best human parents recognize that each child is unique, and has an unique destiny in the world; then it is the same for God.
This ought to be obvious from the fact that God made this world with an extraordinary variety of people in an extraordinary variety of situations.
Indirect evidence comes from the work of spiritual evil in the world now; which attempts to make all Men, all over the world, The Same (i.e. 'equal') and compelled to the same (demonic) ideology of value-inversion.
Form an inner perspective; this means that a Godly life should Not be regarded as living according to a universal template. While there are some things (sins) which we should strive Not to do and repent when we do; this does not apply to the positive agenda of what our mortal life is for.
Our specific life is for us to learn some-thing (or things) of need for our eternal resurrected life; but that need will vary greatly between persons.
After all (to take one example); many die in the womb or childhood; while some live the full biological span or beyond it. Since God sustains us alive, such vast differences in lifespan strongly imply very different life tasks among people.
We each need to ensure that we personally learn what we most need while alive - and fail in this is to fail in mortal life - to waste our mortal lives.
If we are still alive, this means we still have something very important to learn. This is the positive agenda for our own actual life; and it cannot be read anywhere but we each must discover it.
So, if you are feeling bored, directionless, that your life is futile; then You Are Wrong. It means that you have, so far, failed to do what needs to be done, that you are (to a significant extent) wasting your life - and finding how and working on it, is what you ought to be doing.
