Read the following problem-solving process:
Calculate: $(-\frac {1}{30}) \div (\frac {2}{3} - \frac {1}{10} + \frac {1}{6} - \frac {2}{5})$

Method One: The original expression $= (-\frac {1}{30}) \div [(\frac {2}{3} + \frac {1}{6}) - (\frac {1}{10} + \frac {2}{5})] = (-\frac {1}{30}) \div (\frac {5}{6} - \frac {1}{2}) = -\frac {1}{30} \times 3 = -\frac {1}{10}$

Method Two: The reciprocal of the original expression is $(\frac {2}{3} - \frac {1}{10} + \frac {1}{6} - \frac {2}{5}) \div (-\frac {1}{30}) = (\frac {2}{3} - \frac {1}{10} + \frac {1}{6} - \frac {2}{5}) \times (-30) = -20 + 3 - 5 + 12 = -10$

Thus, the original expression is $-\frac {1}{10}$.

Given the above problem-solving process, which method do you think is simpler? Choose the appropriate method to calculate the following:
$(-\frac {1}{42}) \div (\frac {1}{6} - \frac {3}{14} + \frac {2}{3} - \frac {2}{7})$.
