The engine of growth is daily inventory.
Asking genuinely each day which emotional reaction was most deranged and which practical act of commission or omission was most amiss will produce 730 insights or so a year.
That's more than enough to drive ongoing growth.
What is required, however, is honesty and the insistence on not continuing to accept flaws that one might previously have parked for later because, at the time, there were bigger fish to fry.
All fish, eventually, have their turn in the fryer. Once it's a fish's turn for frying, be fried it must, or it will start to stink.
