I started studying Spanish in college and now I'm fluent 4 years later. I had a lot of friends who would speak Spanish with me so it was pretty easy.
Also, I think Spanish is the easiest language to learn. Everything is pronounced as it is written, unlike French or English. And it shares the same Latin alphabet as English.
So learn the alphabet as soon as possible and how each sound is made with each letter. Spanish is very easy to read. It's not like Japanese, Arabic, or Russian, where you have to learn a completely new alphabet.
Start with basic verb conjugations, and with very common verbs like "to have," "to be," "to go," "to speak," "to want," or "to say." There's a book called 501 Spanish Verbs that's really good for this.
Learn basic useful phrases such as "How do you say (this) in Spanish?" or "What does (this) mean in English?" "What is this/that?"
Also, keep speaking as much as you can. Watch TV, listen to music, change your default language settings, go to forums, watch YouTube videos, watch movies. Do as much as you can to immerse yourself. If you stop speaking your language, you will forget over time.
I would try to learn one language at a time.
