Starcraft 2 - Game changing tip

If you saw my previous few posts about Starcraft 2, you know that I am not very good at it. To try and improve my game, I have been watching a lot of videos and replays of really good players. Yesterday, I found the tip that changes the game; always be making workers. Literally always. Workers = money and money = army. This is much easier said than done, but at least it's something to work on with the game. Prior to this, I didn't have any goal in the game except not die (which is pretty difficult). It really turns the game around, and it is obvious now that this exactly how the best players became the best. All this being said, I still suck at the game, but I now know how to get better.
