Podcasts as A Means of Learning Spanish

I decided to immediately subcribe to all spanish learning podcasts

A One Year Goal

Well...It may seem like an unrealistic goal, but I am going for it.
After a lifetime (I am in my 30s) of trying to learn Spanish, I am going to do it.
Well....I have not been studying Spanish consistently for 30 years. In fact, most of my life, I have been studying almost everything but Spanish.

What I have done:

Taken 3 years of high school spanish and learned almost nothing.
Basically just memorized passages for teachers and regurgitated stuff without knowing what I was doing.
