Facts are information that is true, not an opinion or what someone thinks but something that can actually be verified and confirmed. The sky is blue is a fact if the sky is actually blue right then, while the comment :I think blue is unattractive” is not a fact but an opinion. Facts are not subject to the whim of the person compiling them, they do not change without proof or evidence.
There's a world of difference between truth and facts. Facts can obscure the truth
We don't grow when things are easy; we grow when we face challenges.
