I suffer from the Total War games where building a balanced army while focusing on your race's strengths really helps. So I just build every building and every unit. I also never scout or harass my opponent even though I know I should. It seems to just be different RTS habits conflicting with each other in my case.
Don't build every building. Not in an RTS like Starcraft. A big part of the game, probably the deciding factor in most games, is simply that one player is more efficient at building stuff than the other. Build what you need to. That said, build enough unit producing buildings to ensure you spend your income.
The golden rules of Starcraft:
1) Spend your income. If you die with 2150 minerals, you die with what could have been 32 marines saving your ass, along with the four supply depots and the extra barracks needed to build them. If there is even a hint of not being able to build units as fast as you receive income, build more unit producing buildings.
It is true that keeping up with your income is not easy, and most players often float a couple of thousand minerals as the game gets hectic. However it is also true that the pros are much more efficient about spending their income and this is a big part of the reason why they'll crush the average player. So do try hard to spend your income quickly.
Gas can be more difficult to spend, so don't sweat to much if you have a big surplus, but consider moving some of the workers onto minerals.
2) Make minimal use of unit queues. The thing about Starcraft is that you have to pay in advance. Therefore, having dozens of units tied up in unit queues is just as bad as floating thousands of minerals in the bank. Instead, build extra unit producing buildings and queue up new units just before they finish. But always have a worker or two queued, you don't want to fall behind.
3) Don't stop building workers until you're near the supply cap of 200. You need lots of them.
4) Expand aggressively. More expansions means more money. The game often comes down to who owns the most expansions. If you've played against the AI you might have been disheartened to see every expansion attacked as soon as your build it. Humans, even pros, are nowhere near that quick at discovering expansions and you can generally expect to be in profit before your expansion is attacked even if it is entirely undefended. Just do it.
5) Never be held back by your supply limit. Build those supply depots, overlords and pylons in good time.
6) Research all upgrades that have a significant effect on the bulk of your army. If you have 50 marines, making them deal 7 damage instead of 6 is a well worth the money. Make multiple upgrade buildings so you can upgrade damage and armour and shields (if protoss) at the same time.
7) On the other hand don't waste money on upgrades or buildings that you aren't planning to use, or only deliver a small benefit. 5 marines do not get nearly enough benefit from an extra 1 damage to justify an upgrade.
8) Use your MULE/Spawn Larve/Chonoboost to boost mining/production.
You'll notice I didn't mention scouting. This is because, according to pro player Destiny, if you are below diamond league you have much more important things to worry about than strategy. To prove it, here he is on a smurf account playing his way into diamond league with the mass queens every game, and often telling his opponent he is going mass queens. Mass queens are a terrible strategy, and he could never beat a player his level with them. Yet he wins and wins anyway, because none of his opponents manage their economy as well as he does.
I watched through it a while ago and I remember he lost one game because he himself made a stupid mistake, he researched the wrong attack upgrade. In another game his opponent built thors which are really strong against queens and he cheated a little by building other units. But it was mostly him dominating with mass queens.
So learn to make big armies fast before you worry about what you're building.
