More followers and likes on Instagram, how?

[Maria]

I've had instagram for more than a year but it's not until now that I've started using it. I have like 4 pictures, 50 followers and i'm following 25. I don't want to follow more people that follow me. I have good pictures and I don't overtag them if you know what I mean, only tags related to the picture. I've never gotten over 12 likes. So i'm wondering how to get more likes and followers, and I mean real followers. Those who follows me know never likes or comment on my pictures and they've been following me since i got instagram. Does it take time to get followers? My goal for now is 100.
