I built my own little thing, forgive the initial data, was a joke with a friend:
https://fulfillment.now.sh/2017/10/19
On its own, probably doesn't make a ton of sense, but with some explanation, its really awesome. Helps me track not just "todos" but what I want "to be".
I find working on becoming something, rather than doing or achieving stuff brings me far more fulfillment.
Other than that, google inbox "snooze" feature is amazing.
