Not sure why but for some reason I tend to have a tiny army syndrome. I usually play Terran and I suppose the answer may be slightly different for different races.
What happens is that I like to attack early and put the pressure on but there is not a lot of units early on, they either get killed or get spread out so that when mid game comes I don't have a sizable force. I want to be able to make a large army quickly so I can push but I don't want to have to wait too long.
Is there any way I can not sacrifice the early 5 minute attack and still manage to have a large force building up? I want to keep pushing in more and more units every time not just trickle them out until I get attacked and have nothing to bring to the battle.

Watch that video. It will answer all your questions.
To highlight the main points he makes, it's all about macro play. Make sure you are always building a new worker. As soon as the last one finishes, build a new one. If you have way too many, expand and split them up.
Make sure you have enough production buildings so that you can build your army quickly enough. You should never have to queue units and always be able to spend all your money (which should be plentiful since you're always building workers). Hotkey all your production buildings and get in the habit of cycling through them to see which are idle, and then make sure you un-idle them as soon as possible.
Make sure to watch your supply and build quickly enough so you never get supply blocked. You always want to be building new units.
