Smart people are smart because they do things that set them apart from the crowd. While you may be trying to be sympathetic, pointing out that someone looks tired is just another way of saying “you look like crap!”
Surely, nobody wants to hear it, and saying it just makes you sound insensitive and rude. It is however different and better when you say “How are you?”. Someone who is tired won’t actually be able to tell you about their baby that’s keeping them up all night.
That way, you’re letting the person you’re speaking with direct the conversation, so you’re less likely to step on their toes.
“I utilized my phone.”
Saying this makes you sound like you’re trying too hard. It is better you make use of Simple and clear terms. By so doing, you give off the impression that you know what you’re talking about.
While there is nothing wrong with trying to improve your vocabulary, you however should try to keep your speeches sweet and short.
Saying this phrase especially in the workplace indicates that you lack the technical know-how for a job or motivation at work. Instead, say, “I’ll try”. It gives off the same vibe. If you’re asked to do something unfamiliar or intimidating, don’t give up before you’ve even started.
A smart person wouldn’t! They will figure it out, even if they needed help to do so. There’s no shame in asking for assistance so you can get something done, and done right.
Saying the word “whatever” or the phrase “I don’t care,” even in a pleasant tone, makes you sound less than smart because it implies that you don’t have any thoughts at all. There is nothing intelligent about that! Even if you’re just trying to go with the flow, you can still contribute to the discussion.
If you have an opinion, share it politely. If you truly aren’t sure about something, ask questions and seek more information until you can give a thoughtful, useful response.
“This is the way we’ve always done it.”
Smart people are almost always open to new ideas and suggestions. Sticking to a method or process simply because it’s familiar will only make you appear more stubborn and close-minded that smart.
It’s always nice to be willing to listen when someone presents an opportunity for improvement.
“I gave my best advise.”
You can advise someone, but you can’t give advise—only advice. There is a need for you to be cautious of certain words that makes you sound less smart than you really are.
Some common mistakes include adverse vs. averse (the first one usually means unfavourable, while the second one means feeling opposed, such as “I am averse to giving anyone unsolicited advice”); continuously vs. continually (without ever stopping vs. repeatedly); and farther vs. further (the first one is about physical distance, while the second is about figurative distance).
“Any other person feel this way?”
If you want to sound like a smart adult, it’s best not to talk like a child. You should only refer to yourself with certain endearing words when you are with family members, at home.
“That’s not fair.”
Crying foul over something you feel is unfair can very easily make you sound immature or whiny, not smart. Standing up to real injustice is smart and admirable.
But your tone matters. Instead, say “I think it would be better if we did it this way.” And be sure to propose a solution, instead of just fussing around.
