Is it hard to learn Tagalog?

I've been living in Hawaii for 12 years now.I am fluent in speaking Ilocano and I can understand a little bit of Tagalog.I am mostly Filipino and have a bit of Spanish blood.I am also planning on attending a college in the Philippines.What is your opinion on learning Tagalog?
What I hate about the language is that my family and relatives always use it when they're talking about me.

What is the fastest way to learn Tagalog?

What are your suggestions for learning tagalog, I can get the gist of what they are saying, but I am not certain. Can't really speak it either
Thanks Po!
Thank You for the replies, while anyone who voted for emersion into the filipino society head first would be the quickest, I can not afford the ticket just yet..booked Hawaii another story. I will vote for the best answer that will help me now, and anyone that does a search! And RadioactiveFemale and GtrMae maybe we can talk sometime. Again Thanks to All who responded I wish I coud give you all some extra points!
