Do what you want to do in life, not what your parents want you to do (should have done this when I was in college).

Wear sunscreen. Every day. You don't want to see wrinkles at the age of 25-30.

Take responsibility for your own mistakes.

Learn how to write and speak correctly. People will notice if you dont- especially employers.

Don't spend more than you earn. You may want to go crazy at Neiman Marcus, but keep an eye on the wallet. That being said, if you DO go crazy there, start with Miu Miu shoes. They are the most comfortable of all designer shoes. :)

Yep. I love Neiman Marcus.:)

In case of inclement weather, use the restroom before starting your commute home. Living just 2 miles away does not matter when you have a snow storm that renders all hills useless and causes hundreds of drivers to abandon their cars. Those two miles become 3 excruciating hours. Which would be excruciating anyway, but needing to go to the bathroom makes it that much worse.

a part (of), not apart (of)

would have/should have/could have, not would of, should of, could of

to/too/two - not the same things, folks

your/you're - same as to/too/two

Lily already covered the use of "its" and "it's". Someone else caught their/there/they're.

Good idea: study the use of apostrophes, semicolons, and colons.

Eats, Shoots & Leaves is a must read.

Just because a word is "in the dictionary" doesn't mean that it's correct or acceptable to use it. Read the entire definition.

I replied to the incorrect advice thread, saw this one, then had a little mini panic attack thinking I posted bogus info in this thread.
________

A simple thank you note with correct spelling and grammar can go a long way. Put some thought and effort into it, even if you are thanking someone for the mismatched pair of socks that don't fit.

Burning a bridge may seem "fun" but you never know when you might need that bridge again.

When trying a new product that goes on your skin (Nair, makeup, lotion, etc.) do a small test patch first. It's no fun when your skin blisters.

Take a shower, brush your hair, and dress neatly for job interviews. Do not eat messy foods before and check a mirror before going into the interview, arrive on time, early is better.

DO NOT leave your laptop or wallet unattended in a building that has a long history of theft.

Sometimes little old ladies really do steal your cart by accident. Mistakes do happen, even when the contents of the cart are totally different. Acting like a spy with your coworker to track down the lady with your cart in Costco is fun. Then you can laugh about it later instead of being annoyed.

The ultimate in advice:

"If I could offer you only one tip for the future, suncreen would be it."

^ For real.

Computer-speak is only cute for so long.

Learn to relax your face while putting on makeup or doing your hair. That grimace you usually have while putting on mascara will haunt you with deep wrinkles as you age.

And I can't stress this enough:
If you're put in a parallel parking situation, and are fortunate enough to get the first or the last space, pull as far up or back as far back as you can, so the person who has to park in the middle doesn't have to bumperkiss you four or five times!

Don't speak badly about someone next to you in a language you assume he or she doesn't understand.

You may be in for a surprise.

A deal is never "one day only" if a contract and a signature is needed.

"Myself" is a reflexive pronoun that is used in a reflexive context, or to provide emphasis.

Reflexive:
"I work myself too hard".
"The detective himself was the killer".

Emphasis:
"You like chocolate, I myself like vanilla".

All other uses are INCORRECT.

Do the research for the paper now.

No lie: If you get a burn and no burn cream is available, use toothpaste. Any fluoride toothpaste (preferably with baking soda) works just as well as Neosporin. Ice may make your skin blister, but toothpaste willl calm the burn, even if it's already begun to blister. It's like magic!

I was told NOT to do that. All you do is cook the burn.
