My advice is: if you want to be smart, every day try to learn something new or question something you thought you already knew. Even if you start out with less natural mental ability than average, you'll eventually pull ahead of most people. It's just like the skinny kid lifting weights. He might not ever become an olympic athlete, but he can still end up a lot stronger than the average guy.
The boss drives his men; the leader coaches them. The boss depends upon authority; the leader upon good will. The boss inspires fear; the leader inspires enthusiasm. The boss says 'I'; the leader 'we.' The boss fixes the blame for the breakdown; the leader fixes the breakdown. The boss says 'go'; the leader says 'let's go!'
I remember an old interview with the photoshop guru Kai Krause. He was sharing all his knowledge in a series called Kai’s Power Tips. And he was asked why he shared all his knowledge. “You’re giving away your best asset”. He answered that he wasn’t. He was giving away yesterday’s knowledge. He was already working on something new. (And what’s he doing now? Living and working in a 1000 year old castle. With a priceless view and lots of space.)
Í grendinni veit ég um vin, sem ég á,
í víðáttu stórborgarinnar.
En dagarnir æða mér óðfluga frá
og árin án vitundarminnar.
Of yfir til vinarins aldrei ég fer
enda í kappi við tímann.
Sjálfsagt þó veit hann ég vinur hans er,
því viðtöl við áttum í símann.
En yngri vorum við vinirnir þá,
af vinnunni þreyttir nú erum.
Hégómans takmarki hugðumst við ná
og hóflausan lífróður rérum.
"Ég hringi á morgun," ég hugsaði þá,
" svo hug minn fái hann skilið",
en morgundagurinn endaði á
að ennþá jóks milli okkar bilið.
Dapurleg skilaboð dag einn ég fékk,
að dáinn sé vinurinn kæri.
Ég óskaði þess, er við gröf hans ég gekk,
að í grenndinni ennþá hann væri.
Sjálfur, ef vin þú átt góðan í grennd
gleymdu ekki, hvað sem á dynur,
að albesta sending af himnunum send
er sannur og einlægur vinur.
