What Carmine said... but I would suggest you set goals... short term and long term. Maybe there's a specific song you'd like to eventually be able to play, or a finger picking pattern you want to learn.. its just good to have an idea of where you want to go with your guitar playing, so set some goals and that will give you direction.

One thing I'd really recommend is giving yourself some creative time with the guitar every day. Practicing chords and scales are great, but you also need to process that information so that it becomes a reflex or instinct rather than a deliberate thought process. So take time every day to just make music, using what you already know, no matter how simple or limited it may seem. You can make a song with two chords. You can create a melodic solo with just a few well placed notes. You can come up with your own riff using just one or two strings. Experiment, & have fun. This will probably inspire you, and cause you to redefine your goals, set news, and the journey continues. It sure helps avoid "practice without purpose" rutts! :)
