Don't trust anyone nor anything ever. Always verify everything, or take risks if beneficial.

No confías en nadie ni en nada, nunca. Siempre compruebas todo o, si es provechoso, hagas suposiciones y tomas riesgos.

WEF is always wrong.

Also Spanish, because English does not have a word provechoso that defines positive results without implying any comparison/superiority over the past state nor others.
