From the perspective of failure modes and consequences:
I need to spend 100X more time weeding the garden than I do looking at seed catalogs.
I need to spend 100X more time practicing discretely pulling my hog-leg (with every combination of clothing) than I spend discussing ballistic gack.
I need to spend 10X as more time practicing shoot-move-shoot than I do poking holes in paper under perfect conditions.
I need to spend 100X more time exercising than I do choosing the very best food.
I need to spend 100X as more effort rooting out internal parasites than I spend worrying about external ones.
I need to spend 100X more effort maintaining what I have than shopping for new.
Feel free to add to the list...
