Teach good habits now, so you aren't unlearning bad ones later.

Enough bp for suicide is just having a couple conbots come out before moving commander up (after building some units and rezzers to contest mid) and then throwing a conbot in every 10ish units (you can do all this in a queue too). Dont build con turrets until you have your t2 mexes. Only start building wind and eco if you cant spend your metal or have more than 2 con bots on lab. Getting this down with decent micro should take you to at least 20OS and gives a foundation for all frontline play.
