This is just my 2 cents. I learned spanish in 4th grade and grew up speaking it so I learned naturally. I don't know the best way of learning spanish but here is my thought. When you start, focus in the pronunciation of the vowels and consonants. Spanish is one of those awesome languages that it is read the way is spelled. If you know how to correctly pronounce each letter you have just laid a great foundation. So many times I have heard people speak very good spanish but unfortunately with an atrocious accent. I you can speak very little but with an impeccable pronunciation, that will give you confidence and perpetual motivation. ( because you will get good feedback and praises, and you will like the feeling you get from talking to people etc)
I wish you luck!
