I am guessing that you already know some rock songs, me too I have a lot of chores but I make it a point that I can practice at least 10-20 minutes a day (I know, I know, I need more time!), but it's better than having no practice at all. For me, I think I have a different approach, I am more hooked now on music theory than learning new songs (I don't know why!), but when I see some tabs and chords online I can play them not that good but it's better when I started learning to play the guitar within the last 6 months.
Just practice and I guess do not count the days, months or even years, I believe that playing the guitar is a lifestyle already.
