The central belief of Skepticism is that there is little we can know with absolute certainty. There will always be a second opinion or a different perspective.
The Greek Pyrrho of Elis, and the Roman Sextus Empiricus thought recognizing Skepticism is the best thing philosophy can give us.

Skepticism - we know very little with any certainty

The Roman Sextus Empiricus further developed the idea of Skepticism. He thought everything we claim to know was open to doubt and added that there could be no possible way to resolve this challenge. For Sextus, both opinions are equally valid.
Recognising the limits to our understanding is deeply comforting. We can let go of dogmatically defending views we have no way to know for sure are correct. We can still aim for something but also accept we may never succeed.

Skepticism rejects the false hope for easy answers

Pyrrho is considered the first Skeptic philosopher. He thought we waste so much time and effort demanding solutions where there's only doubt that we're destined to be unhappy.
Instead, he thought we ought to adopt a position of suspended judgement, or epoché. If someone asks you for your views, you ought to simply demonstrate epoché and say that you only have your opinion and conclude that there is no absolute answer.

Adopt a position of epoché

Skepticism is the philosophy that there's very little that we can actually know with any certainty. Pyrrho is considered the father of Skepticism, and he believed we ought to suspend our judgment on all those things to which we can never find an answer. By giving up the dogmatic pursuit of some kind of resolution, we can be at peace with ourselves.
