:yup:, God has personally designed his creations, including the life-form known as the “human being”. Nothing we do, think, or say will surprise God.
According to the Catechism of the Catholic Church
vatican.va/archive/ccc_css/archive/catechism/p1s1c1.htm
The desire for God is written in the human heart,]because man is created by God and for God; and God never ceases to draw man to himself. Only in God will he find the truth and happiness he never stops searching for:
The dignity of man rests above all on the fact that he is called to communion with God. This invitation to converse with God is addressed to man as soon as he comes into being. For if man exists it is because God has created him through love, and through love continues to hold him in existence. He cannot live fully according to truth unless he freely acknowledges that love and entrusts himself to his creator.
We human beings were created to know, love, and serve God. To live a simple and profound existence with God’s infinite oceans of loving light.
God’s plan is simple, but we and the fallen angels complicate things.

You are right in saying that committing sin is a God-given right.
God gave us and the angels many privileges ,including the privilege to decide if we would wish to be friends with him.
Sin would be any thought, word, or deed that damages our relationship with God in any way, making him an enemy rather than a friend.
Yes, we can indeed achieve things apart from God, but remember: we should only attempt to achieve such things if they don’t damage our eternal relationship with him.
Earthly achievements are fine, but because of the Fallen World we live in, they can be deadly snares for eternal life, so be
careful.
Building Skyscrapers is fine, just don’t make them like the Tower of Babel, where the goal is to surpass God in some way. Being a famous singer is fine, but
don’t fall into the capital sins of Greed and gluttony.
Earthly achievements won’t last. “Heaven and Earth will pass away, but my words will not pass away.” :bible1:
Don’t make them your primary focus in everyday life.
Recall the Nativity . Christ came down in the form of an infant, in a stable, in humble attire. By the time he ascended into Heaven, he took the right hand of the Father, and became Christ the King. :heaven:
