Hebrews 5:12-14 (KJV) "For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat. For every one that useth milk is unskilful in the word of righteousness: for he is a babe. But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil."
In truth, one step at a time is not too difficult. I know that small attempts, repeated, will complete any undertaking.

“Universe Has 2 Trillion Galaxies, Astronomers Say”
Hubble telescope images from deep space were collected over 20 years to solve the puzzle of how many galaxies the cosmos harbors.
The surprising find is based on 3D modeling of images collected by the Hubble Space Telescope.
There are a dizzying 2 trillion galaxies in the universe, up to 20 times more than previously thought, astronomers reported on Thursday. The surprising finding, based on 3D modeling of images collected over 20 years by the Hubble Space Telescope, was published in the Astronomical Journal.
Scientists have puzzled over how many galaxies the cosmos harbors at least since US astronomer Edwin Hubble showed in 1924 that Andromeda, a neighboring galaxy, was not part of our own Milky Way. But even in the era of modern astronomy, getting an accurate tally has proven difficult.
To begin with, there is only part of the cosmos where light given off by distant objects has had time to reach Earth. The rest is effectively beyond our reach. And even within this "observable universe", current technology only allows us to glimpse 10% of what is out there, according to the new findings.
"It boggles the mind that over 90% of the galaxies in the universe have yet to be studied," commented Christopher Conselice of the University of Nottingham, who led the study. "Who knows what interesting properties we will find when we observe these galaxies with the next generation of telescopes?" he said in a statement.
Using deep space images from Hubble, Conselice and his team painstakingly converted them into 3D to measure the number of galaxies at different times in the history of the universe. The analysis reached back more than 13bn years - very near the time of the "Big Bang" thought to have given birth to the universe.
A galaxy is a system of millions or billions or stars, held together by gravity, with planetary systems within them. Using new mathematical models, the astronomers were able to infer the number of "invisible" galaxies beyond the reach of telescopes, leading to the surprising realization that the vast majority are too faint and far away to be seen.
When the universe was only a few billion years old, there were 10 times as many galaxies in a given volume of space as there are today, the findings suggest. This in turn suggests that "significant evolution must have occurred to reduce their number through extensive merging of systems".
