They mean exactly the same thing. However, in my experience, "too" is usually placed toward the end of a sentence, while "also" is usually placed at the beginning. "I also like to sing." "I like to sing too."

"I need to be sure that I understand what you mean."

The use of pull off is good, but it's "everything" not "everthing"

Noah Gundersen, Penny & Sparrow, The Head and the Heart, Bear's Den, Josh Garrels, Beta Radio, Nickel Creek. These are great bands I like a lot!

Writing about the best chapter of a book I´ve never read

For me the most memorable chapter in the novel "Don Quijote" is when don Quijote mistakes windmills for giants and tells Sanxo that there are true giants that must be defeated. Then they arrived to a hostel and inside there is a girl named Aldonza Lozana who she works as a waitress and he tells Sanso that she is her girlfriend.
This is a chapter that will hold your attention and move you as well. The style that Cervantes uses is quite different from anything I had ever read before and it has made me think about the strengh of our beliefs and convictions to achieve our goals.

Very good English :) let me know if you're interested in English lessons!
