I want to learn to speak Czech. Where do I start?

I am Slovak so I can understand Czech very well. Generally, to be honest, I think that for people whose first language is English or sth like that, Czech might be a bit difficult to learn. And it is not widely spoken so it might be a problem to get a course. But I would try the Internet websites and different textbooks if they are available. And if it is possible you should visit the Czech Republic for at least a year. Good luck!
