If you make a hiring mistake, make the change quickly. Don’t ignore problems. Don’t assume it will get better.

The biggest mistake that you can make is to believe that you are working for somebody else. Job security is gone. The driving force of a career must come from the individual. Remember: Jobs are owned by the company, you own your career!

You hired for scale too soon. The most consistently wrong advice that venture capitalists and executive recruiters give CEOs is to hire someone “bigger” than required. “Think about the next three to five years and how you will be a large company” is how the bad advice usually sounds.

I think it is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive.

The biggest mistake most people make is to not see themselves and others objectively, which leads them to bump into their own and others’ weaknesses again and again. People who do this fail because they are stubbornly stuck in their own heads.

one wrong hire is far costlier than being one person short.

El arte de delegar es una de las habilidades claves que cualquier emprendedor debe dominar. “Contrate gente que no tenga sus debilidades”.

Learn how much confidence to have in your people — don’t assume it. No manager should delegate responsibilities to people they don’t know well.

As success drives the need to hire new engineers at a rapid rate, companies neglect to train the new engineers properly. As the engineers are assigned tasks, they figure out how to complete them as best they can. Often this means replicating existing facilities in the architecture, which leads to inconsistencies in the user experience, performance problems, and a general mess. And you thought training was expensive.

Early on I realized that I had to hire people smarter and ore qualified than I was in a number of different fields, and I had to let go of a lot of decision-making. I can't tell you how hard that is. But if you've imprinted your values on the people around you, you can dare to trust them to make the right moves.

The better a man is, the more mistakes will he make - for the more new things he will try. I would never promote a man into a top level job who had not made mistakes, and big ones at that. Otherwise he is sure to be mediocre.

Not scheduling your time will be one of the biggest mistakes you can make.

The worst mistake a boss can make is not to say "well done".

Hire people for things you are good at.
This way, you’ll know exactly what to look for in a candidate AND be able to evaluate that candidate’s work meaningfully.
