Ruby,I will approach you !

Today , I was glad to talk about ruby with a new friend . I think he is an expert of Python. And he said he still like Python better ,although he is studying Ruby. So , this is a good opportunity for me ,I think :) 
How can I  learn Ruby quickly and well ？ "Sticking to use is the best way !",the new friend told me .
Thx!
