Free Writing well (for the rest of us): No Grammar. No Rules. Just Common Sense. by Alex Eckelberry

interesting that “incorrect usages” of the “selfies” have been in use
by reputable authors for a long time in English. As a reference, I quote this
article from Slate Magazine’s blog:
    “You seem like a better version of
myself.
    I just want to be myself.
    I haven't seen any myself.
    I myself haven't
seen any.
    Myself, I haven't seen any.
    You would even say that to me
myself?
    There are two others here besides
myself.
    He asked William and myself to do it.
    He was a man as big as myself.
    Myself, as director here, will cut
the ribbon.
    William and myself will
be there.
    Myself and William will be there.
    I asked myself what
I could do.
    I directed all inquiries to myself.”
    The author continues: “…all of the above examples have been
in common use in English for as long as there has been an English language
(written records go back 1,500 years)… But not all of them are considered
acceptable in formal usage by everyone today.” [12]
    Still, stick with the simple “reflexive” rule. People will
get irritated if you use the “self” pronouns incorrectly. And it sounds stuffy
anyway, and you don’t want to sound pretentious, do you?
    “I’m doing good.” “I’m good” and “Think Different ” Get your grammar freak on, because things are going to get a bit hairy
here.
    What’s wrong with this picture?
    I am doing good.
    Or
    I’m good.
    A lot of people think the use of the word “good” here is flat-out wrong .
    Actually, there is nothing wrong, at least grammatically
(even though I personally dislike the use of the word “good” used here).
    Why do some people get upset? “Good” is an adjective.
Adjectives modify nouns , not verbs .
    Here, people will say that “doing” is the verb, and that so
you can’t use an adjective to modify a verb. Instead, you should use an adverb  (like “well”) to modify a verb.
    Except they are a bit wrong.
    Good is actually modifying “I.” only because there’s a linking
verb  there (“am”).
    Linking verbs do not express action. Instead, they join the subject  with the predicate (the predicate – from Latin, “to assert” – tells us
what the subject is or does).
    In an odd twist of English grammar,
if there is a linkingverb between the subject and
the modifier, then you use an adjective. It’s called a predicate adjective [13] .
It’s an adjective which is predicating (asserting) what the subject does.
    This is why English grammar can become so hated.
    However, I do think that “well” is a better word choice: “I’m
doing well.”
    You make the decision.
    Think Different Now, regarding “Think Different.” experts agree that it’s obviously
supposed to be “Think Differently” [14] .
And, I agree. It’s just Apple being cute in marketing.

However, there are two arguments that supposedly make it acceptable.

One is that “different” is actually being used as an adverb.
I have personally consulted several large dictionaries, and find this argument
to be absurd.
    There’s a different argument, coming directly from Steve
Jobs:
    “They debated the grammatical issue: If ‘different’ was supposed to modify the
verb ‘think,’ it should be an adverb, as in ‘think differently.’ But Jobs
insisted that he wanted ‘different’ to be used as a noun, as in ‘think victory’
or ‘think beauty.’ Also, it echoed colloquial use, as in ‘think big.’ Jobs
later explained, ‘We discussed whether it was correct before we ran it. It’s
grammatical, if you think about what we’re trying to say. It’s not think the
same, it’s think different. Think a little different, think a lot different,
think different. ‘Think differently’ wouldn’t hit the meaning for me’.” [15]
    Hmm…I don’t completely buy it. I think they just liked the
way it sounded. It certainly sounds more interesting.
    And so, with this argument, we come to the close of this
book, emphasizing that grammar is not rules-based
