Complex Simplicity

Be skeptical of every piece of information you take in. Question the motives behind why someone is supplying this information with you. Once you're done being skeptical, look for the pieces of the information that could be beneficial to you(most everything has something of value in it). Then read over all of your notes and see what you should take out of it and be sure to take only that out of it. Think about why you left out what you left out.

If you take this approach, and are objectively skeptical of the information presented to you and then look for the "meaty" part of the information, then you have no choice to believe the "meaty" part of the information. You come out with a much better appreciation of the truth than if you had just blindly accepted everything presented to you.
