My way is easier. 
The primary reason (but not the only reason) I say that is that it seems as if everyone nowadays is trying to influence you or separate you from your money in some type of fraudulent or unethical manner. It isn't just the poor and uneducated people that get preyed upon, there are plenty of well-educated people who get taken advantage of in some manner on a daily basis.
Ambiguity and lack of control are two things that people simply have to learn to accept about life. I should probably add ignorance to the list as well. There are many things that I would like to know more about but cannot because of: opaqueness, lack of information, I am not smart enough, I do not have enough time or it is not important enough to me to make the time, etc.
Actually, we aren't that far apart. I don't go around having Socratic debates with myself about whether someone is trying to con me or influence me badly.
Critical reasoning is one life skill but granted it only goes so far as being able to gather objective facts in front of you and make some judgements about them.
Intuition plays a key role ... the brain is a kind of analog computer that weighs things as to their plausibility and likelihood. Intuition says things like, "this is really not a good thing" or "this person seems to be dishonest".
When one's "BS detector" triggers, you then employ your critical reasoning powers to validate the BS detector.
The BS detector (intuition) is a rough intuitive guide that operates at high speed. Critical reasoning is a fine toothed comb that operates much more slowly.
And yes, you have to accept the fact that life is uncertain and unfair stuff happens just because someone planned to get the upper hand.
About well educated people who get taken advantage: the saying goes, you can't cheat an honest man.
Maybe critical reasoning doesn't really fit in a list of skills that college provides. Educational systems don't as a rule teach "looking for what is not there" effectively. A lot of individuals with street smarts don't even have a high school diploma.
