We believe that almost all really good investment records will involve relatively little diversification. The basic idea that it was hard to find good investments and that you wanted to be in good investments, and therefore, you'd just find a few of them that you knew a lot about and concentrate on those seemed to me such an obviously good idea. And indeed, it's proven to be an obviously good idea. Yet 98% of the investing world doesn't follow it. That's been good for us.
A man who knows a subject thoroughly, a man so soaked in it that he eats it, sleeps it and dreams it- this man can always teach it with success, no matter how little he knows of technical pedagogy.
Do a few things at mastery versus many things at mediocrity.
I'm somebody who has to physically experience an environment in order to know it as well as I would like to know it. I recognize this is impressionistic, not scientific. People say, 'You sound like Walt Whitman.' Well, I'll take that comparison.
He who does not see things in their depth should not call himself a radical.
It is is better to know one book intimately than a hundred superficially.
It is better to have a few forms well known than to teach a little about many hundred species. Better a dozen specimens thoroughly studied as the result of the first year's work, than to have two thousand dollars' worth of shells and corals bought from a curiosity-shop. The dozen animals would be your own.
Read everything. If you haven't read everything, you'll never be able to write anything.
The hallmark of a deep explanation is that it answers more than you ask
Geoff Leonard knows more about me than I know myself.
To achieve some depth in your field requires a lot of sacrifices.
The essence of the expert is that his field shall be very special and narrow: one of the ways in which he inspires confidence is to rigidly limit himself to the little toe; he would scarcely venture an off-the-record opinion on an infected little finger.
All the people I've met, many outside of cinema, knew everything perfectly about one thing or one subject or one area.
If we develop in-depth knowledge, it will enable us to give our best to others and help to make a better world.
Make yourself master of one single subject and the time must come when your knowledge will be valuable.
To understand matters rightly we should understand their details; and as that knowledge is almost infinite, our knowledge is always superficial and imperfect.
I worked closely with Steve Jobs for twenty-six years. To this day, for all that has been written about him, I don't believe that any of it comes close to capturing the man I knew.
When people rely on surface appearances and false racial stereotypes, rather than in-depth knowledge of others at the level of the heart, mind and spirit, their ability to assess and understand people accurately is compromised.
I try to do as much as I can. I probably knew more about Earl Mills than anybody on earth besides people who actually knew him.
Solidly know content you feel passionate about and that your audience needs to know.
A contemporary or near-future book is much harder because you can't fake the facts. There are people alive who know much more than you do about the subject. You have to really have your research together - and of course no one can know everything about a topic.
When I came across something I liked, I wanted to find out as much as I could about it. This was as true of hearing Hoagy Carmichael for the first time as it was later when I first heard Boulez.
An expert is one who knows more and more about less and less.
If you merely focus on what we already know, then it's not revelatory. You may as well just go and watch a documentary or a few videos on Youtube, and you're good.
Speak seldom, but to important subjects, except such as particularly relate to your constituents, and, in the former case, make yourself perfectly master of the subject.
