I take issue with slide 7 insofar as they aren't right when talking about irregardless. Irregardless is a more-emphatic 'regardless'.
It's use is best like this:
Kid: "I want to go to the movies, and I have enough money"
Parent: "regardless, you have not finished your homework"
Kid: "but my homework is easy! I can do it later"
Parent: "Irregardless, you are not allowed to go to the movies until your homework is finished."
Or
Grown Infant: "Donald Trump is NOT my president!"
Grown Adult: "regardless of your feelings, if you are an American he is your president"
Grown Infant: "But I would never vote for him!"
Grown Adult: "Irregardless - he is still your president"
I have a couple language pet peeves:
The word "That" and especially "So that".
For example:
"She said that she went to the store"
No. No. No.
"She said she went to the store."
And
"We have to take the van instead of the car so that we can fit everyone in (my ex sure has no problem fitting everyone in, that dirty dirty whore)"
WRONG.
"We have to take the van instead of the car so we can fit everyone in"
Etc.
See also: "In order to..."
I also detest "Same exact" because "same" and "exact" mean the same-exact thing.
"She said the same exact thing!"
No.
This is right: "She said the same thing."
"We found gravity affects both objects the same exact way!"
Wrong, stupid.
"We found gravity affects both objects the same way!"
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
