As you're a beginner I think it would be best if you started to learn basic vocabulary using Duolingo (an app). When I want to reinforce the learning I write the words in a list and stick it on the wall above my desk so when I take small breaks while doing work I can see it. Also, I use an app called quizlet to test myself, highly recommended!
As you get advanced and know some basic words I'd say to start learning some grammar so you can build some sentences. Learnspanish.com gives really good explanations you can use. I'd also say that to keep you motivated you should listen to some songs in spanish and try to understand words in them as you get better and better.
Good luck!
