I've been working on structural ways to make gains in my campaigns and what I achieve. Expanding skill is good, but takes time. Habits and discipline are good, but take time. Structural fixes and improvements, on the other hand, can produce big gains -- and instantly, with relatively minimal effort.
One that I've made, that I'm loving, is having "SelfControl" for OSX always on --

Literally, every hour of the day. There are websites that appeal to me tremendously, but from an objective analysis aren't good for my life. So, they go in my blacklist, and I leave it always on.
I lose a little bit from it, I guess -- but I have better ways to relax and waste time than anything on the blacklist, and other things I'd rather do to build my life. So, SelfControl is always on -- an easy structural fix that's giving me hours per day.
