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.
If you can imagine it, you can achieve it. If you can dream it, you can become it.
Better to remain silent and be thought a fool than to speak out and remove all doubt.
