讀心術 10

Zakolyukina says lying executives tend to overuse words like “we” and “our team” when they talk about their company. They avoid saying “I.”

Personal finance advice

.

If I could only share one piece of personal finance advice to grads or to just about anyone, it would be this:

Only borrow money to pay for things that increase in value.

It’s a short list: your business, your house and your education, mostly.

— Seth Godin

Always make new mistakes, 2.4

失敗的次數無論有多少,都是有限數;但是,由失敗過程所吸收的經驗所帶來的成功所達致的成果,卻可以使用無限次。

(安:這一點在人生攻略中,至關重要。這一點可以引申很多東西。一百樣東西中,失敗了九十九樣,只成功了一樣,遠遠好過你害怕失敗,什麼都要肯定成功才嘗試。)

「肯定成功」的,就不叫做「嘗試」。所以,「什麼都要肯定成功才嘗試」,即是「什麼新的東西都不做」,結果,會令你從來沒有失敗,又沒有成功,白白虛度了一生。

(安:大部分人也是這樣的。)

我的講法,應該作一點修正,因為我見過一些人,不加思索就做決定。他們會犯一些原本只要事先思考一下,就可以避免的錯誤;而失敗後又沒有能力或者沒有意圖承擔後果。那些壞人,成功的話就把功勞留給自己;失敗的話就把責任推給別人。

正確的態度,是用一個有系統,而又負責任的方法去「失敗」。你應該在事前用盡你當時可以得到的資料,來減輕犯錯的機會,降低潛在失敗所帶來的損失。

同時,你又要知道,即是你那麼小心,失敗的機會仍然會很大,因為「你當時可以得到的所有資料」,往往遠少於「成功所需要的所有資料」。所以,你嘗試新東西時,一定要有強大的心理準備,充足的財政預算,來自己承擔後果。

Doppler effect

Consequently, as cs increases to c, the absolute speeds v_e and v_a of the emitter and absorber relative to the fixed medium merge into a single relative speed u between the emitter and absorber, independent of any reference to a fixed medium, and we arrive at the relativistic Doppler formula for waves propagating at c for an emitter and absorber with a relative velocity of u:
