Most important thing period is just max out your economy as fast as possible. Get used to hotkeying your command center and your barracks/factory/starport and keep pumping shit out endlessly (until you reach saturation for workers, anyways). If you find yourself queueing shit up a lot, build more production buildings. The stronger your economy, the more you can afford to slip up.

If you ever have more than like 1000 minerals, definitely just build another barracks. "Average unspent resources" is more important of a metric than you'd first realize; 1000 unspent minerals could be another 20 marines on the field, which would in turn let your kill things faster and incur fewer losses.

At the same time, for the first 10~ minutes of a match, be careful with your engagements, but stay aggressive. The AI will purchase upgrades too, most of the time, so you aren't making things easier by turtling up for 20 minutes.

I have a couple thousand matches in SC2's coop mode, which are basically variations on campaign missions and designed for two players. Constant measured aggression while making sure all your units are being productive somehow is the key to success.
