"Only believe half of what you see and nothing that you hear."

Everything you hear is not nessisarily true. Therefor trust nobody. If you can't believe three fourths of the information you take in then you should not believe anything. Everbody is out to get something from you. It is either you money, your genes, or you precious, non-renuable time.

If someone tells you or shows you something you should always varify it with at least 3 completely diffend and unrelated people. If they all concure what the first person said then it might be true. You should still be caucious in beleiving what they say because their really just out to get something from you.

Be suspicious of everyone. Humans will do anything to get what they want.
