It's all about macro. Worker production, build order, and unit production. Watch games on Youtube to learn how strong players do things. It's kind of hard to teach with pure text until you have a better grasp on things. Best to see it first. Watch the replays of all the games you lose.
Here are some basic things you can try...
Terran: One barracks with tech lab, another with reactor, and mass marauders and marines. Get a decent amount and attack.
Protoss: Get a gateway, gas, and cycore. Then upgrade warp tech and just mass units with 4 warpgates. Stalkers and zealots and sentrys.
Zerg: Mass drones until you have enough for a pool and then get gas and a queen. Get a roach warren and use spawn larva to mass roaches.
For rushes:
Terran: Mass scvs and get 4 barracks. Then make mass marines and go kill your opponent with like 3 groups of marines or something.
Zerg: Don't build any drones. Get a spawning pool as soon as you can, then get 2 more drones. Make 6 zerglings when the pool finishes and attack with everything.
Protoss: Send out a probe first thing in the game. Make a pylon when your psi is 9 (or you have 8 probes and one building). Stop building probes at this point. Get 2 gateways and mass zealots for a rush.
I got rid of some of the details to make it more simple. It'll be 90% as effective.
