I don't have a smart phone, so i'm low on apps, just a few on my i-pad. I'm definitely good at compartmentalizing and focusing on the subject at hand. I notice for my hobbies there is also a flow, like often i will be into something hard for around 6 months and then I will go to something new. Last year I was crushing the tabletop gaming hobby, then transitioned to economic theory/financial manipulations and right now I'm crushing Steemit! peace
