Peter F. Drucker

Wherever you see a successful business, someone once made courageous decision.

There is nothing so useless as doing efficiently that which should not be done at all.

The more people tell you it’s not possible, that it can’t be done, the more you should be absolutely determined to prove them wrong. Treat the word ‘impossible’ as nothing more than motivation.

Motivation is a fire from within. If someone else tries to light that fire under you, chances are it will burn very briefly.

Someday is not a day of the week.

When you want to express yourself, a lot of times words can get in the way.

Rich people have small TVs and big libraries, and poor people have small libraries and big TVs.

Focus on what you can control: your actions. How you react to negative feelings will be the key to your success.

You are what you are and you are where you are because of what has gone into your mind. You change what you are and you change where you are by changing what goes into your mind.

Concentrated thoughts produce desired results.

Successful people do what unsuccessful people are not willing to doDon’t wish it were easier, wish you were better.

I’m really clear about what my life mission is now. There’s no more depression or lethargy, and I feel like I’ve returned to the athlete I once was. I’m integrating all the parts of me – jock, musician, writer, poet, philosopher – and becoming stronger as a result.

When I became proficient as a salesman I was invited to teach new hires.

There were no role models, there were no other people I knew who were dealing with the same issues that I was dealing with. I had no idea if this was a stage I was going through or not. But I go to the draft board in Brooklyn and I fill out the form and there was a question that said ‘Do you have homosexual tendencies?’ and I check yes. But where-ever I was on line I’d see people I went to high school with and I was afraid of anyone knowing this about me so I kept on falling back into line and falling back into line. If you said you had homosexual tendencies they sent you to a psychiatrist. He said ‘I see here you’ve checked the box?’ And I said ‘yup’. He said ‘So do you think you’d have a problem serving in the armed forces?’ I said well you know ‘So many men.’ And I was out of the service.

I quit therapy because my analyst was trying to help me behind my back.

No matter where you are in life, you’ll save a lot of time by not worrying too much about what other people think about you. The earlier in your life that you can learn that, the easier the rest of it will be.

Brainpower is the ultimate leverage.
