-USE HOTKEYS AND UNIT GROUPING
-Always try to keep your money low; low money = high production
-Scouting becomes key to recognizing what your opponent is working toward as you learn more about the tech trees of each race
-Try to establish your favored "solid" build order for each race and commit it to memory by playing it over and over so that it becomes second nature.
-Go back over replays when you lose; take note of any mistakes in your or your opponent's play and adjust accordingly
-Lurk on the SC2 forums on TeamLiquid.net
-Watch some of the more recent Day 9 dailies
-Watch reps/VODs from pros and analyze their strategies
What race do you play?
I started playing Terrans, but I am gonna look into information on the Protoss out of curiocity.
Anyway, I wanted to say thank you for the tips you gave above. It actually helped with my game. I highly reccommend to any other SC noobs like myself to watch your 1st few replays to see what was what. My 1st game, I noticed I had 15/19 units available while my opponent was at 33/40 or something like that. When he finally came over to attack me, he had lots of 2nd level infantry troops and I had no bloody clue how to react.
Another tip I picked up was that after building your 1st barracks, build a few marines for defense and go to an addon asap. I liked the Tech Lab so I could build Marauders but the giant mech at the end of the battle was what won it for me.
Also, RALLY POINTS!!! I cannot speak highly enough about these. They saved me so much time and wasted motion during the beginning of the game, I was shocked.
