Yes, it is helpful. My English is just middle level. I can't tell which is modern-day English and which is ancient English yet. I need to study more. Thank you so much.

Good question. As you correctly pointed out, normally, in modern-day English, we would say "Don't let your business drive you". However in ancient times It was quite common to use the form "Let not... " Remember that this is a QUOTE from Benjamin Franklin (1706 - 1790). Suffice to say, one would rarely find such use in modern English; it was mainly confined to old English writings. A few examples using "let not' are also found in the Bible, as follows: Jeremiah 9:23 - Thus says the LORD: “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, John 14:1 - Let not your heart be troubled: ye believe in God, believe also in me. Ephesians 4:26 - Let not the sun go down on your wrath... I hope that helps. :)

Here is a question about the grammar. It seems say "Don't let your business drive you." is more common and easy understand for me. Could you explain it that why use "Let not"? Thanks.
