Yep!

“It is inevitable if you enter into relations with people on a regular basis…that you will grow to be like them. Place an extinguished piece of coal next to a live one, and either it will cause the other one to die out, or the live one will make the other reignite. … If you consort with someone covered in dirt you can hardly avoid getting a little grimy yourself.”
~ Epictetus

We unconsciously become what we are near. If you work for a jerk, sooner or later you might become one yourself.

If your colleagues are selfish, sooner or later you become selfish.

If you hang around someone who is unkind, you will slowly become unkind.

Just look at the fraying of basic manners and human civility we’ve seen in America.

Few things are more important in life than avoiding the wrong people.

It’s tempting to think that we’re strong enough to avoid adopting the worst of others. But that’s not how it typically works.

The changes are too gradual to notice until they are too large to address.

Over a long enough timeline, bad people eventually destroy themselves. They ignore relevant data because it doesn’t agree with them, they take unwarranted risks, they end up alone, without any friends.

They might achieve external success, but they lack inner calmness and clarity.

Just as you watch what you put into your body or your mind, closely look at who you spend your time with.

Are they kind? Are they honest? Are they thoughtful?

Are they helping you be a better person or pulling you down?

Are they reliable? Are they clear thinking?

In short, are they the things you want to become? If not, don’t tempt fate, cut bait.

Distance yourself from the people you don’t want to become.

Cultivate people in your life whose default behavior is your desired behavior.
