You are going about this the wrong way. By trying to do everything at once, you will develop more bad habits that you will need to break then by not having good mechanics in the first place. Everygame there should be a minimum of 3 things for you to improve upon that game.
1: Constant SCV's,
2: Camera keys, F1 - F4, or w.e you have bound them to, use this whenever I want to jump to my expos. Set at the start of the game, if I don't, leave the game immediately.
3: Mineral line saturation, even spread of Scv's, watch the Nodes as the clock gets to 18 minutes, transfer appropriate SCV's. Keep it tight, 16 at three expos is the target goal, not including workers.
This takes care of your macro. If you have a bank early game that isn't good, once you have nailed these basic mechanics, then set new goals, Banking minerals, production vs supply vs income, timing pushes. These will get you to the build order, the production management and the production of units. This might be your next logical step as an example.
Trying to do everything at once without having a real focus for what you are trying to do and instead leave yourself admonishing your mistake after mistake through the entire game will erode any confidence you have, you will feel lost and probably make some asinine post on B-net showcasing how clueless you really are to improving. There are lots of resources out there, maybe you should have asked for those instead.
the camera stuff isnt important, your definition of macro is more along the lines of income, and micro is very important too.
I agree with Anesthetic. The camera portions aren't too important until you hit high plat/diamond. I noticed you are in Gold: This is the time you should be working on one or two things you are having a problem with in the early-mid game. Not getting supply blocked, keeping saturation on bases, keeping up production cycles, scouting and learning timings, stuff like that.
Additionally, micro will start to matter more now. Having good macro will get you pretty far, but getting micro down well, especially with good macro, means that you are that much further ahead of people at your level.
Having just started 1v1ing again for the first time since May or early June, a lot has changed, and I find myself running into all sorts of problems. Now, I am having constant problems with supply blocks, which I didn't really before. I know it is hard to break bad habits, but there is hope if you are willing to work on the problems you have. Forget about winning or losing for a while, and just buckle down on a few things you have seen problems with. Using myself as an example, I need to work on learning when I should throw down extra production, when I need to build supply as every race, and keeping all my production cycles going. So, for the next while, that is what I will focus on. If I get demoted, will I care? I might get a bit mad for a while, but if I really belong where it is trying to stick me, I will get moved back where I am.
