If you know a bunch of programming languages already, what are good ways to learn a new one?

Learn by DOING, not by reading. Work on progressively more complicated programs. Some example ones to try:
- number theory
  - add up all the numbers from 1 to 100
  - read in a number, and then print out its prime decomposition
  - print all the prime numbers from 1 to 1000, using the Sieve of Eratosthenes
