I already use and love Google Calendar, but the "Life Buckets" principle has really helped me to organize it into something much more useful. I'm also working towards not opening emails until I'm ready to clear them out. I applied this to my work inbox first and already am breathing easier!
I've also jumped between bullet journals and google keep for tasks and notes - which made me realize those things can be separate. Rather than not knowing where my to-do list begins and ends, it's all written down, and google keep is for things like movies I want to watch, books I want to read, etc. I always know where to sort the information.
I want to continue paring down my inbox, and streamlining my google apps to keep things organized and stop letting events slip through the cracks.
