Just pick any 1 base build and try to hit timings. http://www.sc2builds.com/ My experience back in bronze was basically doing 1 base all ins. But timing I try to hit exactly.

^ That works too but replays and having a friend who plays around the same time as you so you can get the idea of how to play comes in really handy.. Oh and try playing with A.I. in a straight up game to get a rough feel of how it handles.. Helps a lot

zerg is hardest race to learn . go learn Terran  most easy race to learn u can start buully ppl with simple MMM , <MMT etc

good luck

Hey hey hey.. Don't spoil his spirit.. Play Zerg dude, it's the fun-est race to play.. But you have to understand the distinctive race differences and if you don't wanna hit the ladder yet, you can always just go play some custom games.. More often than not you'll meet someone who's just messing around..

From my experience, if you're new, just do like one-base timing attack. This is very effective if you're at Gold or lower league.
You can do baneling bust, 7 roach rush and win the game around 6th to 7th minute game time.

1 base ahead of the enemy -> this if you wanna play mid to late game. If you are new, trust me it's hard and you end up losing all the way. But it's good if you can practice early expand and mid game type of play. But for the time being, try to 1 base play cheese game first.

If got bunker, try to bust the another side of the supply depot.

Relying on one-base all-ins won't help you improve much. Learn to play a macro game. Don't think too much about ladder ranking since you're still new. Just master the mechanics first.

Heres a great tutorial by one of my favorite commentators, DignitasApollo

That's a good way to start, try getting the gist of playing the game first, reading BOs and it's like will take you a long way.. Watch Day9 too if you have the time.. Very insightful and helpful for you in the long run..

I started off with terran, I can say for beginners it's really easy especially with timing pushes

I find terran race is the hardest to play later on, followed by Protoss, then zerg easiest.

For now you can choose all-in builds to familiarize yourself with micro and macro first since you're new

Or you can choose the long term route, but you might get demotivated in the process, which is the macro style

only if i go hydras in ZvP

not cost effective unless it's some key tech structure like cybernetics core or whatever that you need to take down really fast.. like baneling bust or whatever.. 

i hug buddha legs when i see banshee flying

build spore (or seer if i not being completely lazy wanna use it) bring queen

usually u can scout this out...

in ZvP, when they go phoenix, spore is the best way to answer it while u keep droning up behind with some queen support as you are quite safe from an attack for some moment...
hydras are pretty bad vs phoenix btw and mutas are too slow for u to get the count high enuff (u need to pop like 10 mutas together)...
ling infestors are a good solution...

in ZvT there is the new banshee expand build into a timing attack which is scary...
again, u would wanna defend with queens and spores due to the same reason above (hydras fail in ZvT and muta are too slow to get early on)...
hold on until u get enuff resource for mutas...

you could just expand, btw.

1. scout better
2. better larvae management, dun miss injects

if u cant do those, change race cause that is how u really play a macro zerg

generally i go for lair at 7-9 minute mark
just held off the 1st push by them

but i also will, on rare occasion, go for a 3 minute lair if i sense heavy gas build opener by the opponent & an engy bay by terran
a sure indicator of Ketroc's Planetary Fortress build with mass ravens (look it up on youtube,u'll see what I mean)
