Answer:
Whatever the mind can conceive and believe the mind can achieve.
Step-by-step explanation:
Start with the letters SFV you know the middle letter is N - aside from "the" which is the most popular three letter word "and" is the second most used three letter word. That means the letter S is an A and the letter V is N. So EAFV would read M ND. You know its not an E or A, that leaves I, O & U. After plugging in those letters you have part of a sentence THE MIND _AN. If you plug in the remaining letters you will see that the letter C makes the most since. THE MIND CAN. With that information you will be able to figure out the rest.
