We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
About the only time I use the word "shall" is when I am cautioning someone about their expected outcome of a decision by saying "We shall see." Now I find out I've been incorrect all my life? Probably too late to change my habit, but we shall see.
There is a similar kerfuffle about the word "presently," which now in common usage is a synonym for "currently" but actually means "in the near future" - i.e., I will be with you presently. Careful lawyers do not use presently in contract drafting.
I learned a completely different rule.
"Shall" implies the inevitable: Tomorrow morning the sun shall rise.
"Will" implies an intention: Tomorrow morning I will leave at dawn.

“Shall” is used for first person singular and first person plural.
“I shall do it.” “We shall overcome.”
You is used in second and third persons singular and plural:
He she, or it will
You (plural) will
He, she, or they (plural) will.
Remember that master of the English language, Winston Churchill:
“We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.”
