"The secret of getting ahead is getting started. The secret of getting started is breaking your complex, overwhelming tasks into small, manageable tasks, and then starting on the first one."
Mark Twain
Mark Twain
And while you really can't necessarily achieve anything this way, you can make progress. So if you decide to say mine minerals on the moon, you can start making progress toward that but it may be that you never do find a ride up and back.
No that is not how you apply this quote, to going to the moon. If wish to go to the moon, you break down the tasks of going there and coming back into smaller pieces and execute smaller set of tasks.
"Nothing is particularly hard if you divide it into small jobs." - Henry Ford
