which techniques should I try to master first?

Hi, I am doing BJJ 4 months now(8 technically but injured for 4). I am wondering which fundamental moves I should be working on most. My offensive game is horrible but I'm quite good at defense and escapes. I've been working on triangle chokes and arm/knee bars mostly, plus I love arm bar from williams guard and I love flying scissors... so those are the things i do. What should I be working on adding to my repertoire. I'm white belt 1 stripe. I can do omaplatas and gogaplatas and some gi chokes too but I'm not as good with them.
