If you are already up to speed with many programming languages then getting into Ruby shouldn't be that hard. Some syntax is a bit quirky (blocks in particular) but if you are solid in OOP then you soon see the beauty of the core class setup. The primary difference to Python is that everything really is a method call on a object (even if that object is a class). To master Ruby I would start with toy problems such as Advent of Code.
