If you enjoyed watching football then it's not a question you'd really have to ask as you'd have been watching it growing up like everyone else. It's fine not to like a particular sport and not everyone finds it interesting, but if you genuinely want to get into it now then you'll probably have to pay a fair bit of money every month to watch Premier League or other big European League games. You might be able to find some streaming sites, especially in a local language, that allow you to watch for free but chances are they will be shut down eventually. I take it you have a favorite team that you support? The fact you've not mentioned it already is a bit unusual because that's what people speak about first - but watch a few different teams and decide if you like any of them.
Those who watch football don't really know how others struggle to do what they do. Someone once asked me that, how do I enjoy/manage to watch group of men running up and down and chasing after a round object on a green grass. Some people even get bored and sleep off while watching a game. Truth is, I never liked football until few years back. I think I started finding interest when I started listening to football analysis over the radio. And today, I can confidently say that I have watched the entire game that the team I support played through out this season without missing any.
TV subscriptions are sometimes not always possible because of power issues in some countries. I prefer streaming my games. Anyone can certainly start watching sport. All that is needed is just interest.
