It is easy to be surrounded by people who give only comfort.
It is easy to like people who only say great things about you
It is easier to make choices which will give that comfort.

But that only ensures, you might be in an echo chamber. Your feedback loop does not contain any critical feedback. That kind of engine will run out steam one day. You can try to avoid truth, but you can’t run away from it. Sooner or later we all will be confronted by reality.
