I usually have a really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really bad habit of saying building something will costs too much resources, then get bored of manual mining, but then I dont have enough resources for a quarry (Usually the diamonds and/or gold) + 3 hobb steam engines + an aqueous accumulator (Seriously though, the quarry will auto fill the engines with the coal it mines, so you will never have to refuel it once it gets down to mining coal.) then I get bored of the game, then I log in a day later, work on a few pointless things that don't do anything for me, then get bored again. Sadface.
