Yes and yes: 31 Things I've Learned in 31 Years

&#62; 31. Act like you know what you're doing<p>gold.

There is a saying that the "one who doesn't know speaks and one who knows doesn't" Ever had a situation that someone was talking about sth. that you are an expert at and when you say sth. about it they still insist that day know better or disagree even if they don't know anything about it. After a while I observe those kind of people and don't say anything until they finish their talking. For me, it shows that the person doesn't know anything in the world just acting through the world. So "act like you know what you are doing" doesn't really work.

For all the male-centric things I read everyday, it was actually quite refreshing to read a female's '31 things I've learned in 31 years'.

Sunscreen indoors, questionable.

<i>17. Don't buy the cheapest version. Buy the second cheapest</i><p>Hasn't this been written about many, many times? How restaurants/bars/everywhere-else-on-earth realise people do this, so put an item with a higher profit margin in this spot?
