I would say God has told us and given us what His plan is; but we are never satisfied and want our own special individualized plans. There is one plan, and that is God's purpose. Which will be achieved with or without us.
There is the one major plan, to bring glory (and ourselves, and as many as will come with us!) to the foot of the Father's throne in the end. That part is easier to think upon.
The search for our own special work to do for Our Blessed Lord, in this life, however, can be a challenge.
