About this: "My suggestion to you is that it is wise not to trust anyone."

If we all decided to "trust no one", companies would not grow because the employer doesn't trust the employee. Couples wouldn't get married. No one would travel outside of their home country because foreigners "aren't to be trusted". A world without trust is a sad one to me.

I think it would be wiser to develop trust within yourself. A person who doesn't trust their own mind or decision making damn sure won't trust anyone.
