After the age of 25, cells begin to deteriorate at a faster rate than they renew. Basically, you don't start to die until you hit that age. I concur that despite the immense amount of knowledge I've yet to acquire, and all the wisdom I'll never know, I do know a little something.
I'm a sucker for a good set of organizational skills. Like a child, or a dog, I like routines and structure that work like compasses. Something that really helps me stay efficient even when I don't really feel like it - and especially when I don't know where to begin - is neatly going over my lists. These lists are all found in my trusted bullet journal.
