So far, I have covered "doubting God's Word", and "God doesn't want you to enjoy life".
Today's trick is covered by the same verse as the last one (Genesis 3:5, "For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.").
I believe this is probably the second most common trick -- "You will be as god".
This is the key behind so much bad theology/philosophy. Atheism has aspects of this: kill God, and man can ascend the throne.
What more is there to say? Satan uses it because it works. "Find the divine in you", "have faith in you", "believe in yourself", "your divine spark", "live your life as you please".
