Even as a progamer is macro the most important part. E.g. I’am able to win vs low/mid Master only with pure macro and attack move, but once the skill is even it doesn’t work anymore. But I beleave you wanted to say something more like this:
Around mid Plat you should add more to your gamestyle, like: micro, harrass, multi attacks, improved scouting, reading builds… Until then you should only focus on your macro. Just added this part so there is no confusion. :o)
Reading builds is simple. Every number is your current supply, but as Zerg it’s just slightly more complicated. The best thing is to include some benchmarks. Like watching the VOD of the build and around 4:00 he has X amount of Worker and on 5:00 I have to have Y amount of worker. You will need your benchmarks, otherwise it’s hard to improve.
I can only add 1 more thing to tRQwade’s post which is pretty damn accurate. One of the best and helpful post in this forum, thumbs up. Play! Once you know your builds you have to play them over and over again. If you don’t force yourself to play, you maybe won’t overcome the ladder anxiety, which everyone has at a certain point. It’s all about “keep going”
If you stuck you need to ask some playesr and then over time you will improve.
