Top 10 Most Useless and Misused Pieces of Common Advice

Sometimes even if something is possible it is not necessarily worth it. For example, if you had a really tough piece of firewood that you couldn't split with a normal axe, you could hire a machine to split it, but it really would not be a good use of money for just one piece of firewood.

Most "motivational" videos in a nutshell. If you feel like you have hit a wall to the point that you can't accomplish anything further despite trying multiple times, and/or you realize pursuing a goal isn't worth it, sometimes it's better to give up and try another door.

If I see something is impossible, I will give up regardless of people telling me not to. If I see I can do it, I don't give up, again regardless of this "advice".

I think this one's used as a Jolly Joker if people are run out of ideas.

Playing roles in front of others can be part of being yourself. In addition, what would you think if the doctor told you "For me only two things are important. 1. I don't have a headache, just you. 2. You pay for your visit."? He would just be himself.

Actually sometimes you have to accept some unrealistic dreams can't come true.

I can't make my dreams come true cause they're about magically growing wings, flying, and not dying right away in Fortnite

This literally means: Don't improve.

People (mis)use this phrase for consumption. It's the opposite: for me it is about enjoying the part of life that does not stand on money or worries: nature, art...

Yes, but not to the same extent. This is another misleading sentence very common in quotations that wants to mean "Don't want to be better."

OK, in a WAY, this is false. Just let me explain:
Looks don't matter about how other people should be treated, if someone is ugly, then that's fine, and you shouldn't be ashamed of yourself if you're ugly.
But if you're trying to find a date, it's best to make yourself look attractive, because good looks are the attention-grabber.

Since this advice isn't time, it doesn't help (assuming only time helps).

I don't like anything just because the others do. I don't like anything just because the other don't.

Still less overused than Don't go with the flow.
