I am tired of Romance languages, and I am just learning a language to have fun and just to speak 2 languages or more. Will Eastern European languages be easy to learn?

Examples:

Polish
Slovak
Slovene
Czech
Hungarian
Russian
Serbian
etc...

Does knowing Latin make it easier to learn Polish?

I have been thinking about learning Polish and I currently am taking Latin, its only my first year of it but i feel i am doing rather well. But I would just like to know if knowing latin gives you an edge when studying latin. I do believe the Cyrillic Alphabet is a lot like the Latin(Which is also the alphabet for the Romance Languages give or take a few letters)
I knew that Polish wasn't a Romance language, but I can see why you may have thought I didn't know that. Thanks to the both of you
