An invariant reference frame
can be introduced as follows (Herbrews 1:10-12)And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands:
They shall perish; but thou remainest; and they all shall wax old as doth a garment;
And as a vesture shalt thou fold them up, and they shall be changed: but thou art the same, and thy years shall not fail.
While observing waist and decay, waisting and decaying myself, doing lots of unsensibilities and not doing any good, it is importrant to have a proper reference.
