compared to English, its really harder. but if you learn it, you'll see that it has beautiful meanings, inspiring poems and very interesting grammar.

It's so easy to learn till you attain an intermediate-advanced level, but if you wanna be fluent in Persian or you wanna go further and understand Persian literature yeah that would be a little hard! take a look at easypersian.com

I have no idea either. But looking at it, Farsi uses a phonetic script, that will make it much easier to get an idea of the language. Next, I presume that Farsi has many loanwords as it is an indo-European language. Must be fun to spot them once you can read.
