Learning game is actually most fun thing that there is...
after you learn alot of things you also will have to learn how to use them tho
after that you will probably start looking at each game as if it would be some kind of dance or ritual of balance between power and mass, production-tech and eco, defence and offence, balance between each faction with occasional tech skips and air switches, balance between risk and effectivness of upgraided commander in combat and safe play or even eco play with RAS...
at some point some one will abandon balance and go for all in attack, or full t1 / t2 / t3 /t4 spam with no alternative plan or go for snipe
being able to do that can helps alot in game, but players that keep playing normally and keep developing eco and infrostructure and keep scouting will always have small advantage...
I guess i just dumped some of my random thoughts into this post...
also want to let you know that when i started playing ladder on gpg-net long time ago, i lost at least 10 ladder games in a row... then i learned that i need to make units to survive...
then i started to learn more and more things slowly, and getting better.
(you can always watch some one else play and steal their build order or steal their tactic/strategy, as soon as you will able to execute them you may start understand them and start developing your own strategies)
Anyway good luck in games
