I think scouting your opponent is the best advice to begin with.
seeing and reacting to there build.
if you have a general idea of how other builds work and what the timings will be you can react better.
some games might not be possible to get a FE, some might.
Make sure you have good map control before you move any SCV's out to a expo.

We can practice if you like, always fun learning that way.
