4 of billionaire Ray Dalio's top career tips: You won't be successful 'if you can't tolerate being wrong'

One of the co-chief investment officers at one of the world's largest and most successful hedge funds has stepped down.

He will remain with the company as a mentor, a role he has cultivated publicly over the years as the author of several educational books on career and investing advice.

In light of his long tenure at the company he founded, here is a look back at four pieces of advice he has adopted over the course of his career.

In order to be successful at your job, you need to be good at making decisions.

The ability to analyze different points of view is called radical open-mindedness.

He writes that before you make a decision, you should allow for the possibility that you might be wrong. He tries to get people who disagree with him to understand their reasoning. He needs to look at all viewpoints and relevant information before making a decision.

He writes that the more open minded you are, the less likely you are to lie to yourself.

Idea meritocracies are the most fulfilling places to work. The best ideas win in these environments.

He writes that "the most meaningful relationships are achieved when you and others can speak openly to each other about everything that's important, learn together, and understand the need to hold each other accountable to be as good as you can be."

Internal disagreements need to be respectful and constructive. It's not okay to be dishonest or bad-mouth your coworkers.

Everyone in the idea of meritocracy needs to be respectful of the process. If the idea of meritocracy doesn't produce the decision you want, it's never acceptable to be upset.

Fast talkers are people who articulately and assertively say things faster than they can be assessed as a way of pushing their agenda past other people's examination or objections.

Don't let yourself be intimidated by these people. You have a responsibility to make sense of things for yourself, rather than pretending that you know what's going on.

"If you're feeling pressured, say something like, 'Sorry for being stupid, but I'm going to need to slow you down so I can make sense of what you're saying,'" Ask your questions first. It was all of them.
